White clouds hanging out at top of tank...

[karna68]

is this normal? The stay up in the corner near the heater. Sometimes they venture out into the tank but not often. I have 4 of them in a 30g that's currently cycling.

have you tested the water? How warm is the water? What are the parameters?

Yeah, what doll said. I'd also do a water change right away.

White Clouds are sensitive fish when it comes to O2 levels. They need very high levels. It sounds like the O2 levels in your tank are low. That is probably becuase the ammonia and nitrite levels are high. Ineed do some good sized water changes to help protect the fish.

Also they are cool water fisha dn not tropical. So if the temp is high they tend to be listless and hang out at the top where the most dissolved O2 is.
