not at all! the first time I saw little yellows in my tank i was flipping off the walls
the main signs of pregnacy in an Electric yellow will be its jaw, again not opening its mouth, reducing to no eating. I have read that yellows actually dont usually hide when pregnant so i cannot confirm if its a reputable source, from what I have seen It can go either way.
if you see her jaw change shape this is usually a good sign, i think yellows are similar to M.cyaneorhabdos (sp
) in the fact that they bare 10 + young a litter.
so yes there is a good chance your yellows are or will breed they breed vary redily in the right conditions! (mine do so, so much i contemplating a fish nutering! lol j/k)
so yes just keep an eye on the suspect, the female doesnt have to be removed from your tank, but if you are certain she is holding, you will want to move her to save the fry if your tank doesnt have very many hiding spots, as the males get agressive during breeding and may kill even there own litter.
Also dont be alarmed if you move the mother and she seems to be along the bottom with her mouth wide open, as she is gathering the fry in her mouth for protection.
(p.s if anyone knows more about yellows then me feel free to correct me, this is my combined knowlage plus what i have read about the species).
