So I bought 2 angels 6 months ago, pretty much the same size, likely from the same breeding… they were buds, no aggression between them, in the same tank, and fed the same… 6 months later, one is 50% bigger than the other… curious if the size difference could be sexual, as it’s supposed to be hard to tell the sexes apart… I’m not trying to breed them, just curious if that could be a way of telling them apart long term??? They are both Zebra Lace, and lucky for me the prettiest one is the biggest ( they are both gorgeous ) and likely about half grown??? The bigger one is like 4 inches nose to tail, and 6 inches high… the smaller like 3.5 inches nose to tail, and 5 inches high… they are in a 55 gallon South American community tank, with lots of tetras and dwarf cichlids
