My wrasse go up and down and suddenly jumped on my face. Then one day it hurted itself and started swimming weird. The powder tang who loved me suddenly like divorced me and started hitting glass with tail when I came near. More needed

Dori constantly playing dead. I've tried removing her twice from the tank to dispose of her. False alarm.

My Harlequin Tuskfish sleeping in his man cave standing up every night. Sorry for the picture, I have to keep the tank very dark so that it won't wake up the fish

My lone clownfish likes to "porpoise" at the top of the water sometimes.
It's black and white in color (Darwin Ocellaris maybe) so it looks like an Orca swimming.

My hippo goes to the top of the water, gets a mouthful of air, swims down to the bottom, releases the air in the form of bubbles and then chases after them, eating as many as he can.

My Melanarus wrasse likes to swim in circles around the front frag rack like it’s a work out machine. Then plays mayhem w the sand bed in his interpretation of hide n seek.

When I first got him, my clownfish would do latge circles around my 75g at the top of the tank. Only at night I would find him swimming right in front of the wavemakers to shoot himself across the tank super fast. Eventually he stopped doing it. I wish I would have taken a video.

My huma huma does this all day long unless being fed then he’s normal.

Normal is everyone hanging out in the same
General area of the tank .

My porcupine puffer sitting on top of my MP40. First time I saw it I thought he was stuck and freaked out but I realized pretty quick for some reason he likes to perch up there and is perfectly fine lol.

My tank is empty sometimes because all my 12 fish like to hang out in a small corner where the big green bta's live. Why ????

 

[hoffmeyerz]

My smaller clown uses the WAV powerheads like a treadmill....jumping right in front and swimming like crazy against the current before slipping back out for a break then doing it again!
Must be training for a triathlon or something

My 2 yr old clown and neon dottyback often play together.

I'm currently witnessing odd behavior with my mature clownfish.

Yesterday I removed their home mushroom rock and added some new rocks in the area. I assumed they would be a little off for a bit. Soon after doing the work they were paired hanging out together near other corals in the same general area.

Today the male is tucked way over in a corner and noticed the female was tussling with him a bit, not spawn activity at all and he was a little beat up. She has been pretty much been leaving him alone now so hopefully they'll find another spot to settle on.

I take it that it's the males fault they lost the house.
