I wouldn't do pea puffers in a 10... I have 4 in a 29 and they are SUPER small an crap more thing anything I have ever seen in my life. It is heavy poop too
I went the ancistrus sp. route. Like I mentioned I have a very stunted 2 year old male BN. (he spent the first week of his life in a HOT magnum filter) This tank is the perfect tank for him to spend his days. No competition for food, pristine water and really easy to feed him properly.
I have a terribly understocked 125 gallon so if I can try a few new species in that tank and not have to worry about cramming them into a 10g. Thanks again for the help on the Laetacara, I really appreciate it Chris
