I'm thinking of buying a tank just for my 2 widebar dats, What would be the min size for them? I plan to get them to around 10" than move them into the bigger tank.
or you could just get a 180 and they could live there the rest of there lives seeing as no one has grown a datnoid in captivity to its full length. 5 inchs is a long time though, 5 years.
