grind a mix of foods into powder, i use wardleys shrimp pellets, omega one supercolor tetra flakes and omega one supercolor chiclid pellets and like 10% algae wafers. grind it all up into a powder but not too fine that they wont see it, just enough to make it mixable and able for them to eat in one bite. if they are not eating from the surface with other fish put some of the powder food in a turkey baster and shoot it in their direction
a fish really only needs like 1 bite of food a day if even that so as long as you are seeing them eat anything at least once every couple days they will be fine
ive heard they can go for around a week but I've never tested it and probably wont
anyways this is what i did for my embers when the gbr's stole all the food
eventually they will learn the smell of the food and be more ambitious . my embers started to eat like Parana's . the turkey baster method was only temporary for me as the fish learned to associate me with food, I walk up to the tank and they will be ready and looking for food
but I've also been told embers are one of the more brave species of nano fish
so you might want to get more boraras
like most small fish they are VERY shy around anything bigger than them
ime with the exception of embers most nano fish have trouble competing for food with other fish at low numbers because they are so timid and alot of the time unwilling to leave a certain corner of the tank
if you have around 18-20 they would take better care of themselves
just watch to make sure the larger fish arent nipping them
and for live food one thing that always worked for me with , with every fish i hav is chopped up black worms
the nasty **** that comes out when they split is irresistible to fish
just make sure ur chopping them up small enough the fish wont choke.
baby black worms are very small and skinny so that shouldn't be a prob, most lfs sell them for like 1-2$ an OZ which ends up being a large handful. they are easy to cultivate after you have a good colony too
