That's to bad ryangorney...hopefully I have better luck. Same thing here...no problems with my maroon clown, copperband, urchin, etc.
For diet, I feed the fish something different everday (2 cubes a day..one in morning and one in the evening):
mysis, brine, squid, bloodworm, algae (Hikari Frozen)
Salwater Multi-pak (San Francisco Bay)
Seaweed (Ocean Nutrition)
Diced Scallops with added vitamins (Selcon)....picky copperband
I try to diversify in order to meet all of their needs. I have some sponges in the tank, but I haven't noticed the angel eating any of them.
I'm curious...can or do these frozen foods bring in unwanted pest?
Obviously quarantining new fish is important...do you guys QT for several weeks looking for any problems to appear or do you automatically just QT with some copper, formalin, etc?
