Just be glad you don't have a Bala Shark.
If it wasn't for having two light strips on my glass hood [ I have one on the back part, and another on the front part that I have to move to feed. effectively weighing down both halfs of the hood ] he would have gotten out of my tank thrice over already.
He jumps so hard that he hits the glass, and makes the glass AND the light fixture jump up and slam back down.
What is it with these wackjob fish that want to do allittle accelerated evolution into birds?
