I have 2
goldfish in my 55g right now. I fantail/ryukin from Wal-Mart, and one black moor that I got from some friends who were keeping him in a really tiny tank.
The problem is with the moor. His tail is bent (probably from not having enough room) and he's really a bad swimmer. The ryukin keeps harassing the moor like he's a mortal enemy or something. I think that if the moor could swim normally, he would quit, but that he doesn't know what to make of a goldfish who just sits around at the top all the time.
So, to keep the moor from getting killed, I moved him to a 5g with a sponge filter. The problems are
A) The tank is waaay to small,
B) A sponge filter isn't enough for a goldie,
and C) the sponge filter isn't even cycled yet :-(:-(:-(
So, what do I do? I need to somehow nurse the moor back to health before I put him back in with the ryukin. If I did daily water changes, could I keep him in the 5g for a couple of weeks? He had been kept in a tank aroun 1-2g with no filter and infrequent feeding for a couple of years.
I've been feeding them some shrimp pellets with different bits of veggies and occasionally some frozen food. I'm planning on making some gel food soon. What food would be best to get him strong fast?
