i live in LA,CA,USA... the temp is REALLY hot... i tried to put in ice pack to cool down the water temp. but the ice pack freaked out my barbs n platys.. and... how can i tell when my fish is awake or asleep when it stay in a place? when they r sleeping,...will they move their fins like 10000 times per second?!?!? but they stay in the same spot... arr.. when i pat the tank, it can swim away pretty fast without hitting n e things... why r they moving their fins like that??? r they hot n tryin to cool itself by doing that? :-/
