lets list some fish and their quirky habits!

Id sharks freaking out when i do water changes or anything of the sort.

I try to not disturb them but they still go insane :argh
 
Not a fish, but earlier this evening I fed my african dwarf frogs some bloodworms. The frogs frequently mistake each other's feet for food during feeding time which is amusing enough... one of them swimming frantically trying to dislodge another attached to its foot. But tonight they did something especially funny. Two frogs lunged for the same worm at the same time and each got one end. The worm in question was pretty sturdy so they spent fully 5 minutes stubbornly swimming around with their jaws locked together playing tug of war. (In the meantime the third frog was pretty happy with his undisturbed buffet). They started out kicking and pushing (looked like a girl fight) but one of the frogs was weaker than the other and mostly looked like a kite trailing along after the other frog. Eventually it needed air and gave up, and the fatter frog sucked down his prize.

On a fishier note, I've heard convicts pick a mate and stay monogamous for life, but I don't believe this since mine seem to firmly believe in wife swapping.
 
I had an oscar who would put himself to bed if I left the lights on too long. He would go behind his rock and sit on the bottom.

My midas, Sweetie, will get mad and bang the heater if my husband stays up too late on the computer. Sweetie also has his own toys and gets super angry when his toy friend(puffy plastic fish) comes to visit him. He sees that thing and starts zipping around the tank with his fins raised. He also chases it, bites it and will rip it out of your hand and shake it like a dog shakes a tug toy or sock. I need to get this on video. :D

I have a frontosa, Mugsy, who thinks he is a model and comes out to pose every time I have the camera out. (I had a cat who did that too). Before I removed the Kribs who lived with him, you could not photograph that tank without a Krib being in the photo. I had an African cichlid that was like that too, you couldn't photograph the Africans without Froggy being in the photo somewhere.

I have a Jaguar who bangs her heater for attention. One night, I decided to do my homework right in front of her tank so I could watch my new 33 long brackish (which sits underneath her tank on one of those double stands). I was there so long, she couldn't stand it any longer and banged the top of her hood so hard, she got water all over me, the cat sitting next to me, my stat book and my homework! She just about completely ruined the page I was on.

I have a tiretrack eel that takes vacations to the exotic locale of the inside of the Emp 400. I know he's been in there when the bio-wheels have been knocked off-kilter and I've actually caught him coming out of there twice.

I could go on and on seeing as how I have 120+ fish but I will stop for now.

:D
 
Ive got 6 Mbuna in my 55 that nearly splash water out of the tank everytime i walk by thinking that their going to get food...they swear their starving!! Their like a bunch of puppy dogs.
 
my green fire tetras will be all hunky dory one minute then the next my betta charges and they go insane! they all split up from there school and dash around the tank.

and i have one fire green tetra that always will swim in the current of one of my powerheads and it can barely stay in it
