aspear;2632412; said:more might be possible. FishGoneWild has over 20 polys in his 125 i think.
15 sounds like a good starting number though
Keep in mind he is upgrading to a 150g with more floor space than his 125.
He's going to be upgrading in the next month or two.
Jakob said:ill get 15 sens, then MAYBE add 1 Delhezi, 1 Polli, 1x Ornate..
Ornates get big, you will need to upgrade from a 125 because typicaly they aren't wide enough for ornates. You would want a minimum of 24" wide.
For just senegalus/polli/delhezi I would go with 10 to 15, but make sure you have a good shape driftwood that some bichirs can rest on top and beneath, as well as tall plants that curve at the surface of your water so some polys can rest there too if they want.
