The first is just a sponge, they
come and go.

The fist looks like a favia brain coral that is a bit bleached. I have had one in my tank for years. The better the lighting the better it looks. Fuzzy and brown is good for this one. I attached a pic of mine.

Yeah it's definitely a coral, not a sponge, and that looks about right. Thanks bro. I just increased my light today so maybe it'll start to do better

Anytime, you can give it some reef snow or coral food when the polyps are out (looks fuzzy). Btw, I'm a chick...ha ha. Have had this coral for almost 4 years, but most of that time was under standard fluorescents. Trying to get it to grow, ip but its a slow grower. For the last 4 months I've had it under Radions and it is definitely improving.

Good luck!!
