That makes me very sad. I have had my Banggai, at least 4 years. I have had him a long time he still seems super frisky. I will try not to think about his remaining time on earth, and just enjoy his, fun happy swimming around.
Your tank looks really great. You seem to have everything under control. Soon you might get to the point of endlessly adding coral, and not being able to stop thinking about how you can make the tank even better, it is really fun. Sometimes I have to try not to figure out where I can cram...
That is a tough one, I had a blenny, you might want to try nori or the veggie pellets they sell at the stores, but that is a tough fish to keep alive unfortunately.
What type of surface is it? I would think if you spray it on a cloth and wipe the wood cleaner would work fine, it is probably the least strong of all the cleaners..
This is the stuff that is rooted in the rock nothing will get rid of it. It came in on a rock and it has pretty much stayed my params are great and I have no problems other then this. I have had this tank for about four years and it is doing great just can't pull this stuff off the rocks...
