Fungus or water mold typically feeds on dead or decaying matter. I would think the egg has been compromised. Healthy fish eggs have natural defenses that can resist fungal infections to a certain degree.

It's alive !!! You could put a strip of gorilla tape to prevent the light from hitting the substrate. But I agree with you, it's pretty thick.

Yes, it's highly likely that invasive fish species like tilapia will evolve into new, more adapted species over time. If two populations of one species become geographically isolated from each other, they will evolve independently. and may accumulate enough genetic differences that they can no...

It might be just a bruise. Looking at the general appearance, that fish looks great. It seems to be some kind of Fantail, Oranda or Ryukin... Is the color on the top of the head and tail base new ?

What about GH and KH ? If you have large difference between your fish vendor and your water, that should be taken in consideration.

No, .0.25 ppm nitrite in an aquarium is generally not considered that harmful to fish and wouldn't trigger a water change until 0.50 for me. Stress, transport and water parameters discrepancies are more likely to be the culprit under 3 days.

Should've turn left at Albuquerque :)

Only remineralize the water you are replacing, if the water in the tank is already ok, you want to keep it that way. If you go with the volume of the tank, the hardness is going to increase accordingly.

You have a 15 gallons tank. Add 2-3 more dwarf gouramies and a dozen or more neons. If you want gouramies with tetras. You need to disperse aggression. The more important your school of neons looks, tamer the gouramies will be. Adding more gouramies will disperse aggression further. But a large...

It depends on what you are hosting and bio diversity. Nutrients at all level seems be the key. Nature has a way to dilute things far beyond what would be possible in any enclosed environment. All the time I had aquariums, I had difficulty building biofilm, multiple algae where always present...

While I use same brand and model filters or compatible sponges etc. I prefer to seed instead of swapping. I press completely a dirty sponge close of the intake of the new one running in the new tank. It clogs it a little and it's done. You can put back your working media to it's previous job.

Corydoras and Yoyo Loaches can be fed at night. In fact, many fish owners find that feeding these fish at night can be beneficial, as it allows them to feed undisturbed without competition from faster-moving fish. Or you can also create a diversion by feeding the other fishes food that floats...

Even with pure RO/DI water, after you add the minerals they will still react for a while. Wait a day to let it settle. A good technique is to aerate the water with an air stone, RO/DI water has been depleted from Co2 resulting with a more basic content. Bringing the water back to atmospheric...

Just drop them in the water they will swim a good while, Use a turkey baster or a coral feeder to drop in their zone. The shrimps are going to swim a good while after you add them.

How much time do you wait after remineralising the water you use and did you test it ? At the moment if your substrate is actively hardening the water, you have to use "slightly" lower hardness in your source water to maintain the softness of your tank Your new water should stand a while...

Monday report: No fertilizer last week and ran fresh carbon for 7 days. No recordable changes apart conductivity lowered a little, calcium and magnesium are still the same. Nitrate 0-5 ppm. Water is sparkling clear.

While it's true, CO2 from the atmosphere is constantly dissolving into the water at the same moment. If you don't add co2, At some point an air stone increases the surface area of the water, making this gas exchange process more efficient. If the CO2 level in the water is low, the air stone...

Mutagen Ooze could have been introduced in your tank. If the fishes starts do do Ninjutsu or Ninpō, there's a good chance that's what happened ;)

Yes you can move the fishes to your temporary tank and rescape the same day and move them back as soon as water clears up. Do a big water change on your temporary tank and use water from your main tank to do it, then move the fish there. Keep a part of the water of your main tank to put back...

With hard water, you can also add a water softener in front of Your RO /DI setup. It reduce scaling and help the membrane to work more efficiently for a much longer period and reduce filter replacement frequency.

Soylent green for all !!!

The plant cover is thick enough that, experienced adults are nearly or never seen... That's crazy. All I see is a constant flow of babies and juveniles swimming all around. But when I stir up things, They come out and I was really surprised, Big ones that I have never seen... Even once. It's...

After a couple more weeks, the results are really positive, My 3 mods on the Aquaclear really brought the game up. The new intake sponges are doing very well by not clogging and preventing the flow to slow down. Since, my Bio-media in the 2 first stages of the filter cleaned itself alone. I made...

In my shrimp tank I use powdered food extensively and even if I stop the filter for 15 minutes when I feed. My mechanical filter get shot in a few days, So I rinse it pretty often to keep as much as possible out of the ecosystem before it releases additional nutrients and toxins.

Do you know your water parameters hardness, General and Carbonate ? It's a good starting point to find what fish would be compatible and happy.

Be careful with that, there's a risk for the filtration system. If you stop the filtration while dusting and let settle it helps a lot. But if you are not stopping it and it fills with food dust on regular basis, it will turn your beautiful smelling sponges into rotten poisonous dead filth. If...

Is the tank properly cycled ? If not, it is surely experiencing high ammonia and / or nitrite. You have a little too much surface movement. Try to bring it down to the point that you have nearly no bubbles swirling all around. Try to create a surface flow across the tank instead of mixing air...

A good idea is to soak them in water in a bucket for a while to make sure they sink and look how it affects the water. If it start to grow fungus or bacteria you can rinse, brush and replace the water in the bucket. Repeat as needed. Not all woods are "good" in aquariums, try to use the...

Oh no, be patient, At some point you will also start to add liquid fertilizer to compensate. But your setup will be wonderful in the long run.

I used gutters with T5 tubes and they didn't suffer from heat. But today my tanks are a lot smaller and I bought High-end WRGB LED for all of them. I really like the controls they have. And even with them, silver reflector is a no no no...

Your far from "Jungle" let them go !!!

Don't be, many members here have lots of things to do and are not actively monitoring every replies coming in real time. Sometimes a post needs to be bumped before it catches. I used vinyl gutters in the past too and loved the easy going and seamless finish it does. I quickly realized that...

Yes, it will take more time to balance between water changes, but the transition will be smoother for the fish. If KH rise too fast you can do small 10% water change with Seachem Equilibrium only, everyday to prevent KH from rocketing if needed.

Between 7 and 9 is a 25% difference, it's enough to consider. Continue to top off with pure RO and use remineralized water that is near consistent with the results you want to maintain. It might be iffy at first, but don't cut back with pure RO if KH is too high, use water with the target...

If you do large water changes at a fast enough pace that there is minimal swing in KH over a week, I would not add any more buffering agent until it starts to lower between water changes. If there is a big discrepancy between your source and tank water, You could go with smaller water changes...

Difficult to say how long it will "over" leech. But it's a good thing to keep it in check and try to prevent swings. Looks properly capped to me, I think things should straighten up quickly after a couple water changes.

Yes, you're right clay is pretty inert, but the one you have in your aquabasis as been enriched with nutrients.

You nailed it. the clay in the substrate is acting as a natural buffer. If you have a small tank and have a substantial quantity of aquabasis. Depending on how densely the tank is planted, It can influence KH for a while before stabilizing.

It's called Shrinkflation. They where not making money enough, they diluted it more so it last less. Instead of 156 tests your down to 114.

Some intelligent TVs have features to equalize sound, They are called: Auto volume, Loudness equalization or Optimized sound. Check in your TV setup If you can find one of these. If you are using Windows check in your audio output properties enhancement for Loudness equalization. I have a...
