hi
I had my 6 red rainbow fish for just over a year and my biggest one has just died today. I also have a rainbow shark and ilebrevis synthonis but I never seen any fighting or else. Just wondering what would have caused his death? All water parameters were good (checked at LFS)

Any help will be appreciated thanks.

If you mean the one on the top. He has quite ragged fins, and they seem to bit torn, or bitten.

Do you know what your exact parameters were? "Good" is a subjective term.

Were there any outward signs of illness? Behavioral changes? Are your other fish acting healthy?

What are ilebrevis synthonis?

Edit: Just noticed your attached picture. (Getting used to this layout.) To me it looks like it could be velvet or a fungus.

The water parameters I had done a my LFS and they just said good and nothing wrong with it.

I didn't notice any behaviour changes and at the moment all my other fishing are eating and acting 'normal'.

Ilebrevis synodontis are a catfish very similiar to the synodontis petricola.

Thankyou

Did it have any patchy sores on it? It looks like it might have from the picture, but hard to tell.

Hard to say for sure. Dead fish seem to go off really quick. They go from alive->dead but looks normal->Puffy white, fluffy and ragged in an hour or two. Everything will nibble dead fish pretty much.

250 litre tank and I will go and get the exact parameters hopefully today.

There are more suspects than I can list. The fish has started to decompose, and has been scavenged a little. The fins etc say very little, except that the other fish batted the corpse around.
Prime suspects?
Probably not water. We always blame the cycle, but it's rarely the culprit with year old fish.
Red rainbow shark? If he managed to get a good shot in, he would have done it. No doubt, he wants to.
So would another red rainbow male. They fight, and as they age and grow, males become more intolerant. Glossolepis incisus does fight for rank, and they can kill each other quickly. The fish under the corpse is carrying dominant colours... That's a clue. You may a new alpha.
A shark/barb gets nastier with age too. Both would end up in the uncomfortable interview room of the fishy first 48. I would give the Synodontis ilebrevis a break. Not a prime suspect.
He could also have simply died - an organ failure, or any of the same sort of out of the blue bad luck that happens to anything.
