Sorry, my bad, I keep forgetting stuff. For the most part, the coral came out of my friend J's 55 gallon tank and he has a sand sifter right now himself. The coral had a lot of waste, needed bacterias and stuff in it. The people at both Golds and Big Als aquariums in Calgary said they're fine. The one I have is barely 2 inches across right now, and it's gimpy.
Only has 2 actual legs and 3 stumped ones.
Guess it's growing? Took a look tonight at some Goby's at Big Al's in the SW of Calgary, and the people there suggested getting some snails and they suggested getting a scooter benny or a goby for a cleaning crew, and a shrimp in a few weeks.
