That is likely what will happen. I will more than likely end up with 3-4 1-2 inchers and start them off in a 40b. Then a 55, then the 125. But once they make it to the 125, I'd like to have some other fish with them, not just a species tank. I know BP's are not a fan favorite but I have kept them in the past and would like to keep 1 again. And I've admired chocolates for a long time. So if I kept a couple of other big fish in there (BP and Chocolate) I assumed I would only have room for 1 or 2 heterospilas. Would a nic make sense for a fourth fish? I would prefer to keep multiple hets but i figured a 125-150 would only allow me to keep 1 with other big species. Thank you again for all of your help. It is much appreciated.
