I have like an extra 3ft long tank I'm not sure how many gallons it is, it was a gift from a friend but anyways I was wondering what to add to it like what looks cool I already have an established 56 gal. Demasoni and Yellow Lab tank going really well and would like to know what else to occupy the tank with. I was thinking Metriaclima Estherae and an Albino Ps. Socolofi I really like the orange and love the characteristics of the Albino Socolofi but will the cross breed or are the temperaments too much for one another or what would be a better suggestion in general if anyone has any? Anyways this is what's on my mind and would like to know what to go with thanks.
