So my acan has been looking weird the last two days. Looks much smaller and it's mouth is looking really weird. Any idea if this looks normal or what's going on?
looks like something may have picked at the head, possibly to get food out and pissed it off a bit, looks healthy otherwise. all the other heads look fine as well. Nice colors.
if it's white and a skeleton, something is eating it, i had that issue with one of my fish, as soon as i removed it, the coral recovered.
what kind of shrimp and crabs do you have?
i'd put money on the peppermint shrimp. I got rid of mine, they like to dig into the mouths of lps and rip out any food, along with their insides as well at times. They will also tear apart feather dusters.
i too had a peppermint shrimp that attacked my acan a while back....
I would only pull the shrimp once you r sure it's them doing it. It could be something else bothering em. Do you have a sump?
