Not sure if this is the right place for this, but I've been looking for something other than a fish for my aquariums. I have my 20 gallon grow out tank which houses an indonesian datnoid, bullhead catfish, columbian shark, bala shark, ID shark, redtail shark, dragon goby, pumpkinseed sunfish, and a peacock eel. Yes, I know that the columbian shark and dragon goby are brackish, but they are in freshwater until they are large enough for a larger, brackish tank, which I may or may not also add my Freshwater Moray to. Also in my 20 gallon I have a floating dock, where my Iberian Spanish Ribbed Newt is always on, and I also have an albino clawed frog. But I also will soon be upgrading to a 130 gallon freshwater which will house a 15" Pacu, a 10" Florida gar, a 15" Longnose gar, and if my 20" Freshwater moray eel continues to thrive in freshwater, that will also be added to the 130 gallon. I would like a turtle or something like that for the 130, preferably something easy to find, and affordable. As much as I'd love a Fly River Turtle.... it's out of the question. Maybe like a mud turtle or something, but I don't know what species and care. Please help!
