with frozen brine, we just use a knife and scrap some off and give it to the fish. 1/2 a cube is way too much for my two fish, maybe at best I feed an 1/5-1/6
mine love the bloodworms (about 1/4 a pack for the fish), I was told by a few people here to feed bloodworms but now i've heard twice not to...my fish like it and are alive...I'll have to look into it more. the box shows a picture of a clown on it.
the clown also liked the algea sheet i feed when we had a tang
varied diet is best, i try to feed once a day, sometimes twice, the clown does beg for food...I don't worry though if I'm not home to feed them.
