Parasites?

[svreef]

We got this Chromis recently and it looks like his skin is being eaten. What is this? Should we remove him from the tank?

I've heard of that, lots of chromis getting disease at the wholesaler that leaves that red on their sides, and it's one of those thing that wholesalers just can't be bothered to treat it on a fish that they probably sell for $2 each.

chloroquine phosphate in a hospital tank should help out. You can get it in a product called Ick Shield (it's not ich though)

Something to be concerned about though. Since it looks like the fish is in your display

There is no fallow period for Uronema. Once a tank has Uronema, it must be assumed that the disease can survive in there almost indefinitely.

Did you buy the fish like this, or did it develop after you got home sometime?

We got them from live aquaria on Wednesday. I didn’t notice the issue initially but it has gotten much worse. Sadly we didn’t have a quarantine tank (we do now)
