Who is doing the nipping in this fish tank2007-11-24 23:43:43

I have (sorry if I butcher the spelling on these fish)

1 blue gourami (getting pretty beat up)

2 white mollies (getting nipped)

2 female guppies (the 2 males were killed this week)

1 albino bottom feeder

1 chinese algae eater

1 pleco

1 feeder goldfish (easily the biggest fish in the tank)

4 neon tetras (1 is looking pretty bad)

2 danios

4 cherry barbs

I really don't see much nipping going on when i watch. I feed 2 times a day in this 20gal tank. I'm assuming some of these fish just are not compatible with each other?? Which ones? I have another tank I can use to seperate, what should I do?

Answers:

Chinese algae eaters are known to be aggressive, usually when they're older though. I'd have to go with the goldfish IMO.

Now for the lecture :) Goldfish shouldn't be mixed with community fish. They prefer a cool water environment, and they are major ammonia producers, and usually end up snagging all the food.

Your tank is slightly overstocked. Are you sure it's nipped fins and not fin rot? Fin rot is caused by poor water conditions, usually with an overstocked tank it's more likely to occur.

The pleco you have, is it a common pleco? They get huge, too huge for a 20 gallon tank. IMO get rid of or buy a new tank for the goldfish, chinese algae eater, and possibly the pleco if it's the larger one if so replace it with a smaller species ie: bristlenose or rubber lip.
