Oh sorry the tank size is we think a 15 gallon. It was given to us as the previous owner wasn't sure. They just had a turtle in it. It has 14gallons in it now. We only have a one gallon pitcher to fill it with. We cleaned everything(rinsed in hot hot water) I didn't want to use soap because I read on several sites not too? For residue and other reasons I'm assuming.
I think it could be the rocks. They are the rocks his friend gave us that was in a 75 gallon tank. my boyfriend rinsed many times with hot water to make sure nothing was on them and didn't use soap.. I wasn't there so I'm not sure of his procedure but our gourami hangs out around the rocks alot inthe bottom and I didn't start till this tank.
Before this we had two 10gallons.
One had the 6 neon tetras and the weird sucker fish(we got it at meijers and they didn't know what it was?)
The other had the dwarf gourami, the Corydora catfish and the 2 guppies.
So I'm not sure like I said it looks better today because now she is actually lifting them up. But I still think something's wrong. And there are no cuts or scraps. No fuzzy red stuff or anything like that. It's kind of like stuff on the scales?
Or discolored only on the top later?
Sorry if its too much to read :/
