Other than the grazing what did you get them to eat? Any secrets? I have one in qt and going on his second week won't touch food and didn't show interest. Afraid there isn't enough in there for him to survive much longer[emoji27]
Hey. I understand your panicking. Angelfish can be very difficult to feed like we wish they would. Here's what I do when I am trying to encourage a feeding response. I simply start off by offering artemia nauplii (aka baby brine shrimp). Newly hatched BBS are somewhat nutritious for juvenile and adult fish before they absorb their yolk sacs but this obviously won't sustain them. The swimming motion and the size of BBS are irresistible to every fish I have kept that is small enough to target BBS as a food source.
Once you have your fish eating BBS, start supplementing at least 24 hour old brine shrimp with Selcon. Selcon is high in HUFAs and DHA which will be even more nutritious for your fish in QT. Offer live brine shrimp 3 or 4 times a day.
Make sure your fish eats quite a bit of the either the BBS or enriched brine shrimp. I would perform daily 20% water changes if possible. Keep QT water as clean as possible.
Once he is adjusted to eating BBS and/or enriched brine shrimp, then I start to feed mysis that has been enriched with selcon. Mine are already eating cyclopeeze and are grazing on filamentous algae on the back of the tank.
Before you add brine shrimp, turn pumps off. Let the brine shrimp be easy targets so that the fish can eat at will. If you notice in my video, the pumps are turned off and that's why you see them eating. They are locking in on BBS and cyclopeeze.
***One note here - For finicky eaters such as the multibar, I would add several pieces of LR from my display tank to the QT in order for the fish to pick at it for copepods, sponges, etc. They really need an established tank in order to find other food/prey items other than what we offer them at first.
This is just a tip in order to attain a feeding response. Once you have a feeding response along with good husbandry, the fish has a chance. Good luck! If you have any further questions, feel free to PM me.
