I would be interested in a few. I am currently raising 160 genetically altered male nile tilapia, for research purposes. I received them as fingerlings and placed them in 4 seperate 30 gallon tubs. I've had them for about a month and they have more than doubled in size. I've started seperating them by size. I don't want to exceed 12lbs. per gallon, so I have plenty of room thus far and don't for see running out.

Rainman, good pick up on those tanks.
