Nope, just the 2 SAEs and that may be one too many

. When I got them they got along great. The bigger they get, the more they seem to fight. I may have to relocate one when I setup another tank.
They are pretty good at controlling algae. I was told by my
LFS that there are certain kinds of algae that the otos won't eat but the SAEs will. That is originally why I bought them. The otos and SAEs have done a great job at keeping the algae under control.
I added the BNs recently. I bought 6 on AquaBid. I put 2 in my 29 gallon with my endlers and 4 in this tank. I really didn't need more algae eaters in the 38, but I had no where else to put them

. I will probably get rid of a couple of them when they get bigger (
and I can sex them) if I don't have another tank or two set up by then.
So far I haven't had any problem having so many algae eaters in one tank. I do add algae wafers and fresh veggies occasionally to make sure they are all getting enough to eat though. I have never seen the SAEs harass any other fish (
except for each other). The same has been true for the BNs.
