I have had a CBB for about 5 months. He is about 4" now so a decent size. He never lost a lot of weight, but he is slightly pinched behind his head and narrower at the top than in the middle. He has been at about this weight for several months. I hand feed him from a turkey baster every morning and every night. He eats this way for about 10 minutes or so, and it keeps the other fish from outcompeting him pretty well. I feed him until he loses interest, and almost always has a bulging belly afterwards, especially if i suppliment with blackworms which i have been growing in a freshwater setup, but i don't want to deplete them by feeding all the time. I discovered this method maybe a month ago, before that it was kind of hit and miss but he has always eaten ok. But the last couple weeks i have been very dilligent in feeding him twice a day until he loses interest, and he does not seem to be gaining weight. I feed him a mix of frozen mysis and blood worms. Once, i have dosed the whole aquarium with prazi pro, and the last week or so i have been putting metroplex and focus in the food, thinking maybe an internal parasite is preventing weight gain. Is there anything else to try? Should i try dosing prazi again? or maybe the metro/focus doesn't soak into frozen food well enough? I do have a quarantine, and i did QT him in copper before introduction but not prazi. I'd prefer to keep him in the display if possible though because he seems to be happy and there are no behavioral issues between him and the tangs so i'd like to keep the momentum. Thanks in advance!
