no. i have 2 teugelsi, 3 endlies, 3 ornates, 3 laps and 2 weeksii. The weeksii are about ready to go into the main tank (i hope) and are housed with the new teugs with a tank divider. everyone else is in a 240 gallon aquarium. in addition to the bichirs there is a red tail giant gourami and a black ghost knife.
