Mixing Genicanthis

[jda]

Hello,

I have:

a 2 year established pair of Watanabei
2 female melanos where 1 is changing into a male
a 2 month pair of caudos (red sea)

all in different tanks. Since I will soon have 3 pairs when the melano finishes his/her change, what are the chances of 2 of these pairs living in the same tank - say a 7x2x2 210G?

The watanabei circle each other and appear to want to spawn, but I don't know if they ever do. The melanos are young and probably not mature. The caudos are big enough to be mature, but they have not paired up like my watanabei have.

Any ideas or opinions?

Thanks-

id say two is ok but pushing it. i have a pair of bellus in my 180 and i feel like im cramping them. but when i first tried genicanthus i had 2 pair in a 100. they seemed fine until i lost them during the upgrade. i really didnt know better at the time. give them plenty of rockwork, feed frequently and as much swimming room as possible. good luck
