Thanks joea. I have always liked Metriaclima sp. "Msobo" , so a nice grp or those would be great. I already have Acei fry in the 1 inch range from the parent acei in my other 55 gal . So would say 18 demasoni, 6 msobo, and 6 acei or another grp be ok, with 3 grps total? I will have a rena xp 2 and an aquatech 30-60 power filter. If that is a lil much may just stay with msobo and the demasoni. I figure 18 demasoni to start in case I have any loses due to agression.
