I must wonder though...are these interesting aquarium fish? I've always been intrigued by them but they don't seem like they'd exhibit many behaviors in the aquarium...at least while you are looking during the day.
If you're not interested in Pirate perch before you acquire your first fish, I doubt you'd find them to be an ideal aquarium fish. They don't have the snazzy color of darters and the don't have the activity of minnows but I've had great success and enjoyment keeping them in the right community tanks. No doubt this is an oddball fish but not entirely unattractive. In my tanks they don't seem to hide much and become quite friendly to me (after all I am the food source). In numbers they are quite fun to watch. They appear more active than in community tanks and always slowly "patrol". Interaction among other Pirate perches is highly entertaining. I find them a load of fun in community tanks as well. I might be a wee bit nutty though.
While out of town for a week my fish were overfed. I keep them pretty well fed (fat) but when I came home most of the fish had portions of their intestines outside of them. I was horrified to say the least. This condition lasted for two weeks in most and almost double for others. I now have to be very careful with portions since a few have "popped" again after too large a meal. I lost one fish and I'm honestly not sure if this condition lead to it's demise. I hope this will not permanently effect my spawning efforts this spring. I can at least report that Pirate perch are gluttons to the point of a near death experience.
