which one of these fish could be attacking my cls?

pictis cat fish

black shark

bgk

some of the loaches have nics out of them

Black shark would be my pick.

They always seem to fight with fish that look similar to them.

Would have to say the Black Shark would be my pick too

They can be picky little buggars from time to time

I agree. they can be mean sometimes.

id ee with the others and say the black shark i have heard some nasty stories about these over the years.

Don't rule out the Pictus Cat they can be nasty too

i wouldn't rule out the bgk either. they are a carnivore fish.

lol thanks guys and girls so it could be anyone?

I dunno. it'll have to be a pretty gutsy fish to take on a shoal of 50 CL's!

it won't be take on them all, just one or two at a time that might not be with the group at the time. :-?

:lol: point taken

whoever it is , is attacking the larger cl's

I would say black shark

if its only the bigger ones, then i'd say its probably the shark.

clown loaches can do some damage fighting each other 2

ok its been a while and now i can see little bite marks on some of the smaller loaches too

heres one of the medium cl with the marks on its head

could the black shark make little holes like this?

Cheers Matt

Looks like HITH

to confirm it is the black shark (which i think it is) i would take him out and put him in a tank alone for a few weeks and see if the problem is resolved if not then obviously its not so try another one.but i think you will find the problem will go when he's gone.

Looks like HITH

yeah it does look suspiciously alike...

it looks like a fish bite to me. ive seen skunk loaches that do exactly this sort of damage to some other fish.

Your water parameters must be really good if none of them have got an infection with that sort of damage
