i'll admit.. i have now idea how to take care of fish. i've read everything.. but still my tank stays cloudy. but my fish don't seem to care.. i've have one for 3 1/2 years! the other is about 9 months i think. the bigger one is about 7-8 inches long. they don't leave their plants alone. they push them up and they are always floating on top. anyways here are goliath (big one) and hannibal (named cause he was biting goliath's tail off!) they are in a bowl.. cause i was cleaning their house.
