leleupi suddenly getting along ?

[resk]

ive had 4 l. leleupi in a 55 gallon for a few months now.

originally two of them became dominant, leaving the other two with little room of their own

the agression never got out of hand to the point their health was in question, so i left them together

now im seeing these 4 recently becoming much more comfortable with each other.

in fact, i have not seen the smaller two being pushed out of the main area of rocks for a few days

is this behaviour circular, will they eventually become increasingly agitated with each other in 6 months ?

can i assume that i have 2 pairs ?
how can i be certain of the fish sex ?

here they are:

I believe they are supposed to be kept in groups. I think they are rather aggressive with each other while they are juvies, so if they have all matured, that may not be an issue now. You could have gotten lucky too and have two good pairs. Hard to say though, thats great that they are getting along now though.
