Iv been feeding them the culture worms and banana worms which i wouldnt think would be too big to eat not tried them with the brine shrimp eggs as yet as some only come up to take a breath then back down.
Also 99% of the babies are just staying on the bottom only the odd few are swimming about up and down the tank.
I have had problems with the fine stringy slimy algae on the sides of the tank which iv been removing with a clean paint brush.
Iv noticed also that i have 1 red fry with a slight kink in its tail but is managing fine swimming about.
I read most of the things you said on different internet pages also but wondered if anyone knew anything different thanks Kel
