Dormitator cubanus

The Dormitator cubanus lives in the demersal, freshwater environment.

Also Dormitator cubanus and Fundulus grandis (which I never seen in the hobby, not sure if they exist in US). Agonostomus monticola, seems like a good choice, but I also unfamiliar with them and they seems a little too large for my future set up. More
