I will let you know closer to then =) I assume if one of them see's an actual female fish and has a heart attack or dies from stress I'll get a baby look-alike xD But I'm sure you'd take care of them =)
The age might also be the deciding factor. Kalec has been with us 3 months, but was a decent size when we bought him. So I'd say he's definitely 6-7 months. Very active, and he's healthy, despite his eyes looking like popeye =P he's definitely healthy, no worries about that.
Eranikus is younger, I'm sure. Maybe 4-5 months, ballpark...really hard to guess when you get them at the store. He's super active too, but also young xP He doesnt have any problems, aside form spooking and running into his rock. He's damaged a few scales a few times, but everything's healed back very well with no infections.
