It's amazing what you learn after you've already made the mistake. My mother gave my daughter a tiny aquarium that wasn't big enough to hold a snail, much less any type of filtration. So I bought her a 1 gallon instead. I set it up with gravel, underwater filter, dechlorinated the water and let it run for a couple of days. Then we went and bought two goldfish. (I hadn't found you guys (and gals) yet.) My daughter named them Skipper and Tiger. A couple of days later, I was looking up info about goldfish and I found a site that said that they need much more room. So I bought a 10 gal. aquarium and set it up with a much better filter to move the fish into since they were obviously quite cramped. I let the 10gal. run for a couple of days and moved the first two fish into it and then added Splish and Splash--two feeder goldfish. I left the 1 gallon aquarium running although it was empty. Skipper was already doing poorly in the smaller aquarium. His condition has consistently gotten worse. His fins are clamped. He just floats around, mostly on his side-moving with the current in the tank. (He's now by himself back in the 1 gallon.) Sometimes the only way we can tell he's alive is his eyes and his gills moving. When he's not floating, he just sits at the bottom. Occassionally he will swim, but he looks more like a lopsided cork than a fish. I think we are more or less wondering if/when we should euthanize him or if he will recover. I am doing a partial water change every day and feeding him strained peas (baby food). Although I'm not quite sure it is helping any. My other problem is Splash. Today I noticed he has acquired a dark rim on the extreme edge of two of his fins. The ammonia in that tank is at 0 and the ph is about 7.6 (I think). Since I found this site, I added cycle to the tank to help get the good bacteria going and aquarium salt to help cut down the stress. Is there anything else I can do for them. I know I need to get a new/bigger tank for them, but that isn't an option until around Feb. of next year. What can I do? I was going to post pictures of them, but I haven't figured out how yet. Any help would be appreciated.
