Crazy fish..

First topic message reminder :

Last night i just found out the reason why i hear clic noises every night and sometimes in the afternoon while im at home..., they were coming from the 75gl tank.. a clic...clic... clic... and it stops, i tought it was the filter motor taking a du**, but last night i was having dinner and i looked at the tank and got him on the spot!!, the noise was coming from my 4" Male Kenyi banging the heater against the glass with his tail going in circles , im gonna try to get a vid from him but im afraid hes gonna break the heater and cause a big problem, any ideas why hes doing this???

Seen that more than once!

I have a piece of old netting rubber banded around the end to prevent that.
