I have a healthy/ active catfish about 20 to 22in as of today. currently in a 8x2x2 tank along with 2 other aros 1 silver and 1 jar. also a softshell turtle seems to be doing fine with them. i only feed it frozen peeled shrimp at the moment since thats the only thing it will eat. use to eat massive delites but not anymore text me at 408-394-6749 for any more question or pictures. Would ship for right price and if you can tell me the best way to package him last time we moved him from a friends house home he popped the bag and it was leaking slowly but enough to wet my whole back seat
