uro question

[emilsmee]

ok i just got 2.4 juvie niger uros today and was wondering if a 70gal (4' x 2' x 2') is big enough for them all. i'm also confused about whether they're communal or not. they all get along perfectly but a really reputable site says you should not house them together, even a male with a female except when they're going to be breeding. we've had them at the store before and they've always been communal then too... anyway i was just really confused about what the maximum number of uros i should have in a 70 gallon is. i was thinking of splitting them up into two trios (selling off one of the trios because i only have room for the one 70 gallon tank right now). let me know what you guys think or have heard...

thanks,
emily
