So i read inthe second or third post about some Hikiara fry food. I actually have some of that I tried to feed to my baby ghost shrimp. I dont think they ate it though because they died
. But it is a very powdery almost like baby powder that can be mixed with water for it to sink or you can put just the powder in and it floats for a few minutes.
I dont know if betta fry will eat it or not, and Im not going to try on mine for a while (if I can finally get some), but just a thought. Petco has it for $3 for a decent size package.
