Who Gives A Fish Forums

I'd say it's likely a Favites coral. Those things coming out of its mouth probably are feeder tentacles, or maybe it's just stressed from being out of the water, that's why they look weird.

They resemble RPE from Indo, I'd say they're a nice zoa, that green mouth does give it a bit of a PE vibe though.

I'm guessing they must've had a ton of blue LEDs in their tank, 'cause that would explain the crazy yellow color I saw.

Your tank's clearly still in the cycling process or maybe something's gone belly up in there. Either way, it's time to take action, and fast.

You need to do a massive water change, like, now. Have you got a spare tank or somewhere to temporarily relocate your livestock until you get this under ...

No, it's not trying to turn the little one into a female, it's just seeing it as an invader in its territory.

How long ago did you add the second clownfish to the tank?

At this point, I'd recommend temporarily removing both fish, rearranging the rockwork, and then reintroducing them together ...

I've got a solid tank going, my fish are thriving, and I'm not second-guessing my methods. I know everyone's got their own ways of doing things, but I'm curious to hear your thoughts.

A Valentini puffer could work in a 30g tank. It's generally reef-safe, but if it gets hungry, inverts and corals might become a snack.

I agree, low alkalinity can cause issues. Bumping it up might help, could see an improvement.

I've personally had the opposite experience with kryptonites - they've been one of the more low-maintenance corals for me. As long as I avoid relocating them to a spot with higher light levels without giving them time to adjust, they seem to do just fine. But I've noticed that even slight changes in ...
