This hitchhiker came in on a frag and I let it grow a bit. My tang likes to snack on it but it still grows fast. Doesn't spread though. I'll let it grow and just trim it if it's not bad. Extra fish food can't hurt.
+1 on bryopsis. I used tech-m for 3 months with no luck, I just deal with it and rip it out when I can. It grows rather slow for me but I have a lot in my system competing for nutrients.
Alright I'll remove it. It's very isolated so should be an easy remove. Also was checking it out and it's filled with those pineapple sponges I posted the other day.
