hi everyone,
what do you reckon is the largest fish i could pair in a rio 180 (40 uk gallon) 40x18x18?

the rio 180's dimensions are 40x16x20
40 inches long (101cm)
16 inches wide (41cm)
20 inches deep total (50cm)
water height is just over 15 inches if you take into count the sand/gravle and where the water can be filled to, up 2 the black strip whitch is 3 1/2 inches also the tank is sitting on a plastic frame whitch adds fake height

as 4 the stocking i have no idea i just put fish in till i think its enough

OK thanks mate

I think two pair would be alright with those dimensions. Set it up with driftwood and and some line of sight barriers.

I agree 2 pair of firemouths would look good, especially when they started breeding

ok thanks for replys, would it be poss for me to have a group instead of pairs? like around 6 of them

You could experiment with like 5-6 females. With 3 pairs in a 40g you'll run into big problems when they start breeding. Still pushing it IMO.
