well i've just got into breeding neon rainbowfish and have set up a 24"x 12" tank and the eggs have been in there for the most part of 7 days relatively succesfully, now i think they've hatched and are hiding in the spawning mop but i cant see 'em at all! i only have a small sponge filter and an airstone in there so i dont think they've been sucked in to the filter:/ any suggestions?
