My threadfin rainbowfish are extremely skiddish, and apparently when they get scared they nose dive so deep into my valisneria that they get stuck and can't get out. I lost (they literally disappeared) one fish a week or two ago, one fish two and a half days ago, and one fish just today a...

Update: My cory does seem to be healing slowly (black stripes coming back on the edges, more iridescent color in the white spot) . I'm no longer convinced that the wound was ever infected, but the antibiotics are at least keeping it from becoming infected. It's also becoming more and more...

Aquarium salt dehydrates fungus or parasites, causing them to die. It works because the fish is generally less sensitive to the salt than whatever is infecting them. I've never owed saltwater fish, but I believe you put them in freshwater when they get infected. This kills things by...

Of course. I meant that I may switch, not do both at once.

Thanks for the detailed answer! My LFS only had Erythromycin, which is an antibiotic. I dosed his tank with that this morning. Interestingly, he wasn't acting sick before the treatment so it's difficult for me to tell if he's feeling better. I might be able to get Pimafix soon and I'll try that...

My false julii corydora is injured on his left pectoral fin. About a week and a half ago he got both his pectoral fins/bones lodged in the aquarium background and couldn't move. He was so stuck that he couldn't even shake the shrimp off of himself and I had to pry his left fin free. His fin...

Excess mucous makes a lot of sense. I didn't know that! I'll keep it in mind if they ever get hurt again. Thanks for the suggestion with the salt. For non-metric people like me: 1 tsp per gallon is about 1.6 tbsp per 20 litres. Even though that's less than what you suggested, it does seem to be...

This is posted on behalf of my mother. I moved out 4 years ago but I am still caretaker of her fish. I haven't seen the fish in person, but I have some pictures. 10 days ago (Tuesday) my mother sent me this picture of my oldest goldfish: He clearly had torn his tail on something (even though...

As a last bit of information, I did experience another pH spike a week or two later from my CaribSea Eco-Complete substrate (it seems my tank is cursed when it comes to these things). It was pretty significant, but none of the fish seemed to mind at all. In researching a bit more, I found this...

The Krylon Fusion does actually seem to have solved the problem! Shortly after my last post, the water in my tank got very cloudy and disgusting. There was clearly a bacterial bloom that was probably the cause of the pH spike. I emptied the tank, rinsed it, and refilled it completely. I also...

I'm going to keep posting updates here in case someone else who is in the same situation finds it. It seems like putting a coat of Krylon Fusion on 95% of the concrete did not fix the problem, it just delayed it. Or something. My pH still spikes, it's just not consistent in when or how much...

The pH held steady overnight! Going to do some water changes and see if pH consistently goes to 7.8 and holds, or if the tank just needed a more thorough rinse than what I had already done.

I repainted with the same drylok cement because the salt had drained all the color from it and eaten through several layers of concrete. A week later I gave it a coat of Krylon Fusion. Some places are very hard to reach (very close to the glass) and so I know for a fact that, despite my efforts...

Thanks for all the suggestions! I'm going to try to address as many of the comments as I can. I understand that cement leaches calcium into the water, but many many people have had success with this technique. The person in the tutorial I linked had no pH spikes or drops whatsoever, and I...

In mid-January I finished a diy aquarium background using this tutorial. It's a 30 gallon tank, but the background only goes up halfway so I only need about 20 gallons of water to cover it completely. For two weeks, I did 100% water changes every one or two days. Within less than 24 hours, the...

For anyone who comes across this thread, this page has interesting info on how common tb is and general info on tb. What I'm not sure about is how hard I should be trying to prevent the spread of tb, assuming the fish even have it. It sounds like fish can recover from tb. Can I ever again...

In a way I hope it is a tumor or cyst because at least then it isn't contagious. I'm hesitant to keep the danio fry with the adults if it is contagious. They currently share the same water but have no direct contact. Instances of fish tb in betas look very similar to what my danios have. I had...

The water idea is interesting. Over the summer I brought my aquarium to a lake. The tap water there is pumped straight from the lake, fed through a good mechanical filter, and then through a UV light to sterilize it. My cory catfish loved the water and were laying eggs every three or four days...

One of my fish has had a lump on her side for about 6 months and the other has had it about 4 months. I originally thought it was a tumor of some kind, and since it doesn't bother the fish at all, I haven't done anything about it. These fish are all two years old. I have found several threads...

Thanks for the advice. I haven't had any problems with getting fry to survive, though I do consistently have a few newborn fry that disappear. Not sure why since my breeder box is made of mesh so small that even danio fry don't risk falling through. It happens even when the only thing in the...

I've been doing some research on cory eggs and other eggs. I was especially interested in this blog post claiming a 90% hatch rate with exactly the same species of cory. Though it could be a fluke, I'm curious to try a few things to see if it improves my hatch rate. I've read in a few places...

The residue was very powdery, like sand dust. It came off on everything, but was also very difficult to get off the liner completely. All it does is make the liner look gray, so pictures wouldn't be very helpful, and it has also been in the ground for two years. It was advertised as a fish safe...

Thanks! I actually have the API master test kit and use it quite often. We were actually more worried about residue on the pond liner. There wasn't a lot of risk to the fish, but still enough that we weren't about to put a hundred or even fifty dollar fish in there.

I just joined tropical fish forums. I am a college student who enjoys fishkeeping. My start to fish keeping was pretty unexpected. We were weeks away from moving into a brand new high school during a terrible season for ice dams. Water was dripping everywhere and the school decided rather...

I have one female and three male Peppered Corydoras that have been laying eggs like crazy, but I've had very inconsistent success. I always remove the eggs by rolling them off the glass with my finger so they stick to my finger, and then rolling them onto the side of another container. The...
