What would you suggest?

I'd get the new tank now if you can afford it. In three months your fish could be much larger, up to 3 inches a piece.

You know, that is my biggest concern right now. When I got them which was not that long ago, they were tiiiinie tiny. And they are still babies. I was shocked with how fast they have grown, esp the jack dempsey. The pleco has grown too. I have had the rainbow shark (in a diff tank) a lot longer and he has not grown as quick. In fact, none of them has grown as quick. My gsp's I have had longer too and they are barely an inch.
I think im gonna go ahead and get a bigger tank...
