Kept a few. Mexican Milk snake, various Corn Snakes, and a wild Gopher Snake (many many years ago, found it in our truck). The milk snake was the prettiest, but my favorites are the natural colored corn snakes. At the time I kept them I also had to raise the mice to feed them, no frozen mice...

In my brief foray into bubble sizes the most interesting thing I found was that the surface tension makes very small bubbles under significantly higher pressure than one would expect. When I get home I will be looking at this further... For CO2 injection they use quite small bubbles when they...

FYI I just guessed about 4 litre/min. The rating for a tetra whisper 100, what I use, the volume per minute is closer to 3.3 litres/min. This reduces the value of surface area exposure to 5060 cm2 which is under the surface area exposure. If using larger bubbles ie 2mm the exposure is now...

The intent here is not to critique @FranciscoB, but I have heard this statement before starting back in the late 60s with my father telling me essentially the same thing, ie the bubbles really don't play a significant role in the gas exchange other than by causing water motion. I don't...

I don't feel any sadness over this post, I don't agree with all aspects of it but nor do I disagree with all aspects. I have seen a number of posts, some of my own, where we are describing our points of view. In my opinion, overall the forum members give advice that I believe is beneficial...

That is a lot of condensation. If the lamp is an LED with the transformer located outside the canopy there is little danger to yourself from the electricity because it is likely dc no more than 20 volts, with limited amperage. But, you risk getting water into the lights even though they may be...

I don't know about cory eggs and their care, but in all cases putting a foam or very find mesh bag over the filter intake can prevent the fry from being sucked up the filter. As a matter of course I like to use prefilters because they allow the fish another crack at finding the food before it...

The smaller bubbles have a significantly larger surface area than the equivalent volume of larger diameter bubble. Assuming a sphere (bubbles really don't form a sphere) a 1 liter bubble volume would have s surface area of 438.5 cm2, and a radius of 6.2 cm. A sphere of 1 ml volume would have a...

Sorry I use a 407 as well, but I don't know if the canister will work with the 406 canister container.

No but they seem interesting I will be watching this thread

In my opinion there is nothing wrong with glass substrate but it does have limitations. If you work with the limitations you should be ok

I've tried ground glass. Approximately 16 mesh. Very clean Plants grew ok Very light ie got sucked up easily No surface porosity for bacteria It worked well enough in a low stocked tank but was overall not that good. Light penetrates it causing algae where you cannot remove it. Looks...

The black one definitely looks like the female. The eggs turn color in my experience within a day. I too cannot see the male parts, they are typically quite a bit smaller but are still visible soon after fertilization but not long after. The striped angel does not look well his eye looks...

I have purposely added these snails to my tanks, and I am glad I did. They don't seem to get out of hand and the fish get live food from time to time as the young snails hatch. They are pretty mobile and cover all areas of the tank.

I have been using an 20 gallon tank as a plant nursery and I am thinking of using it to keep a small number of Neocaridinas. I have read a number of articles online about them and also the post by @TylorFerretLord and think I am OK but thought I would pass my ideas past all of you. I have been...

I forget that myself sometimes. I have gone through a few trials of maintaining a small tank but eventually, I end up doing something larger. You think it's only 10 gallons how hard can it be?, just as much work as a larger tank, you don't have to move as much water or substrate but you have...

Too bad, it is a nice rock. I would have been proud to have collected it.

When I did work for fisheries we used the same nets you would use for goldfish in a pond. Some of the nets had a d-profile to use at the bottom of sandy substrate or cement pen, or a round profile for other applications, mostly with an approximately 1' square opening and extendable handles...

I believe fish can get depressed. Even though fighting with the goldfish is likely a negative reaction, the pleco now has no other denizens it can interact with, so its environment is not as interesting/interactive from what it used to be. With no external stimuli life is not quite as...

I am good at hatching them not so good at growing the brine shrimp out.

I have used a couple of commercial shrimp hatcheries but found the best to be a simple 1 or 2 litre bottle with the bottom removed and an airline going to the bottom (top) of the bottle. If the bottle is supported, upside down, in a warm location with the air going right to the bottom (i don't...

Tank is looking great. I wish I had your sense of design.

Gneiss rock in the middle of the tank. Did you collect that yourself?

I don't know about 15 gallons, that is likely too small and as @davros suggests the temp will be too high to too low. I run two 200 to 250 gallon stock (think cows) tanks in my back yard without any electricity, filtration, or any special treatment other than a cleaning yearly. One tank has...

Likely calcium deposits if you have hard water, but also other material from the water. Looks like the top of an in tank filter with potentially an airstone underneath. If that is what is is then the water spray collects on the screen and the area with the highest and initial evaporation point...

I have used most types of substrate at one time or another, and I will have to say I still like gravel for some applications and sand for others. There are some miss conceptions and specific aspects that are not considered. 1. Gravel in most other disciplines starts at 2mm average grain size...

The silicone should handle the potential freezing, but there are other factors that are a concern especially if the aquarium has plastic moldings. Depending on the plastic they can become very brittle in cold weather. As well both the silicone and the plastic are subject to UV damage if...

This is really a guess but, I would say they are both males. But as @Ichthys stated there is not a lot of sexual dimorphism in Angelfish so it really is a guess. You will know it if any of them pair off.

I would not recommend the angelfish with the gourami. It sometimes works sometimes doesn't, in my experience it worked for a while then my gourami started fighting with my angels. I cannot speak for the other fish.

My python stop valve also died, the issue in my case was a small amount of sand getting trapped in the plastic ball valve component. I replaced it with a brass valve as others have done and it worked well till once cleaning one of my smaller tanks the metal valve assembly lightly tapped the...

Never had an issue with alcohol though this is likely due alcohol making me feel sick if I had more than 3 drinks at any time. Was a light smoker from about 13 years till my 40th, and haven't smoked since (20 years), but unlike some of you I would have to say I still have cravings especially in...

Personally I find with sand I like the substrate a bit deeper. I strive for 2.5 inches in the front but closer to 5 inches in the back when there is 18" between the front and back. Waste that is not caught by the prefilter tends to accumulate in the front where it is easy to remove if you have...

What is the substrate above the aquarium soil? There are some substrates that are also calcareous, specifically for reef and cichlid setups, that too can be the cause. You will also want to make sure that it is pH neutral. If it is aragonite or something similar it will also cause an issue...

Fish food is not a likely cause of the issue but when the cause is unknown it is good to consider all possibilities.

There are broadly two types of fish keepers and I think they should look at two different sources for fish. We have the recreational fish keepers such as myself, and we have serious fish keepers such as @GaryE. Currently I keep fish for the pleasure of having the fish, watching them interact...

I am not a disease expert. That said your fish looks to be shedding mucus, looks like a time I forgot to put chlorine treatment in the tank during a water change. I would suggest you have something in the water, ammonia, chlorine, medicines. Water change without anything other than chlorine...

I doubt this is a parasite issue it seems to be progressing too fast. Are you suggesting that the red poop is the parasite, or the poop is red because of the parasite, if the former you should post a picture? Right now I would suggest you follow @Colin_T suggestions, short of an autopsy and a...

For me it is the realization it is a hobby not a lifestyle (for me). Had up to 7 tanks due to mts, two 10 gallons, two 20 longs, 37, 60, and 75. Weekend would come by and I would have to maintain all those tanks, this was taking too much time reducing the time I spent hiking and kayaking...

What constitutes the difference between a long fin guppy and a short finned guppy. I am in a similar situation to the owner of the thread and debating how much I should modify the water to meet the guppies needs. In particular I am looking at whether I can get by with passive water amendments...

I am more on the side that a dead animal is not the same as a live animal. The essence is gone once an animal is dead. I put dead fish under one of our balsam trees and the local wildlife usually deals with the bodies before the next morning.
