Multiple Silver Question

Pat,
Tank size is a matter of opinion to an extent but from my experience I think you need a larger tank for them. I've had a 30" in a 750 and added a slightly smaller silver and they got along very well. I've also purchased 3 6-8" silvers and placed them all in the 750 (after I gave away the large aros) and they also did fine. It just depends on the individual fish involved as well as the tank size. I've heard of silvers fighting but have never experienced it firsthand.

IMHO, stick to one of those beauties if you're going for 240g.. For a growout tank, might be viable to house a school (6 or more to disperse aggression), but eventually, u'll need a bigger tank.. ~I learned it the hard way~

Have a look at bderick's video of his 450g if you want to get an idea of tank size for multiple silvers/Osteoglossum. I'm sure he will be the first to say his tank is barely enough, and I believe he has something bigger in the pipeline?
