Who Gives A Fish Forums

Tap water's usually fine if you dechlorinate it. RO's overkill unless your tap's super hard or has crazy high nitrates. My Java Fern's been thriving in tap for years.

Dude, same thing happened to me. I added some Blackwater Extract and they perked right up. Also, keep the room quiet for a few days. Loud noises can stress them out.

I left a few in my tank for a while and noticed my pH crept up. Not a huge deal, but if you're keeping soft water fish, it's something to watch. How often do you test your water?

My experience with mine has been similar, it's always displayed its feeding tentacles throughout the day. I'm curious, have you noticed any issues with your other corals? If everything else seems fine, I wouldn't be too concerned about it just yet.
