Hello all, I have a few acfs and one of them has taken up an odd habit, involving the canister filter, lately. The tank had to be changed due to a crack about three days ago, which resulted in the spray bar being angled slightly differently, though still pointed at the glass to minimize water disturbance. As far as I can tell, the bar is back to normal. One of my frogs has started jumping for (and occasionally succeeding in holding onto for about half a second) the spray bar. This activity occurs most often at night.
The system has been in place for about two months, is around five inches above the water, and is extremely quiet. I'm trying to figure out what may be causing this since the frogs are well fed and outside of the tank switch, everything has remained constant as far as I can tell.
