I bought a long nose butterfly about 5 weeks ago. Quarantined for 4 weeks. He's been in dt for a week. He ate great in qt, real pig, but he's a little skinny. He eats good in dt. My dt is 300 gallon fish only. He has to compete with 4 med sized tangs and 1 other butterfly and several damsels for food. Does anyone have suggestions for a feeding tool that will allow him to get more food since he's a slow eater and it's difficult to compete with tank mates?
