You know Cichlidae covers over 1300 described species and at least as many undescribed species distributed throughout central and south america, asia, africa, madagascar and even as far as the middle east, ranging from tiny 1" dwarfs to 3' alpha predators, living in almost every possible biotope from soft acid pools to lush vegetated zones to hard rocky lakes to brackish and even salt water, and eating all manner of diets from highly specialised feeders to complete omnivores, eh?
Might as well just say "bloated [sic] is only found in fish", although its often found in cattle too I think....
Maybe in stead of "learn as you go" doing research before investing in fish would be a good idea before taking on unknown species?
