the little fish

Those little fish on some ones hand in this clubs trip to a rock pool are so nice!
What are they?
Would we be able to have fish like that?
They look like an eel and a fish in one,do they do anything bad in an aquarium?
They look realy slippery

They are Lawnmower Blennies. Yes you can have them, they are cool to watch, blennies have funny personalities too.

they like eating algae of diff sorts they do have personality aswell .they hid in holes away from predators .i have got one it hitchehiked in on someliverock .i dont know how long it was out of water for but hes cool theyre a peacefull fish also

I've heard your only supposed to have one blenny per tank, but then again colin has five in his four foot, and i've got three different species of blenny in mine and none of mine fight.

My Rockhopper Blenny eats more algae off the glass than the lawnmower does though.

mine is the flake king he loves it i use to have a bicololor dotty back that was the only fish in my tank that picked on the blennie freaking bully it was

I saw one in the shop today,it looked like it had a big smile what a sweet looking fish.
Thats our next one,no doubt
They sound good,thanks all.

Why do they call them a lawn mower fish?

probably cause the can mw a good amount of algae down quiet quickley i hadthe back of my tank full of bryopsis alge and within a week they had cleaned it al off i could see little round shapes from there mouths where they had been all over the glass
