my fire eel is 27in and all thow still a great looking fish colour is nothing like as bright as when he was small. i allso had a tt that was bigger but hid all the time. for a small tank a peacock would be a good choice
Use Red Wigglers! I just got one myself about 3 weeks ago. He is about 8" and he loves these worms... Just dangle infront of him and be patient. He already eating out of my hand by doing this!!!
