I think if you add all those fish/eels to the 240g you'd be stocked. I wouldn't add any more. Maybe a small damsel or two, mainly just as test specimens. You got rid of a 7-8" miniatus for $60? I am only about 45mins from you, wish I would have known about this! I got a 4-5" one for $70 but it died in my brothers tank. He was a bully two for a few days, eating everything, then just died several days after he got him.
