So I’m fairly new to salt tank keeping. I was given an established 30 gallon tank with 2 clownfish and 2 yellowtail damsels, one feather duster worm and a “cleaning crew with some snails and crabs. I had a green bubble algae outbreak and bought an emerald crab. Emerald crab is doing his job and doing it well.. but while I was at the reef/fish store I also fell in love with a little green and purple BTA! I’ve done a couple of feedings with freeze dried brine shrimp and Kent Marine microvert.. the anemone doesn’t seem to be the same color and I wondered what I’m doing wrong? Or if this is normal?
