Quick question...

Is it bad to house two males in tanks right next to each other, where they can see each other all day?

Does this stress them......Is it best to let them see each other only occasionally?

I have a 20long where there are 3 males in a row that can see each other all the time. I haven't found any problems resulting from it.

Only a few tips of advice I can give if that is how you are choosing to house them.

#1- make sure they can't get over the partition... if they can, they will
#2- watch to make sure they are going too flare-crazy. they could blow a fin... that's where they flare so hard they cause their fins to rip.

outside of that, go for it.

I dont think thee is a problem with it i keep several in a row as well in my 20 longs only thing i see that is a problem is they dont flare very much after that unlesss y aget them a new male to look at lol i thik they get bored with each other fairly quick lol
