Although annoying, I bet its quite funny to see a Dovii of that size going nuts?
Not if it was full size though !
I don't know if mine really qualifies as a monster fish, maybe a middleweight Cichlid lol..... but lately I have been cracking up at my Carpintis who absolutely hates me with a passion.
Attacking the glass to the point where his lip is cut open, chasing my hand, picking up the substrate and spitting it against the glass and ruining my displays.....he has major behavioral problems.
