How big would a dovii get in a 210 gallon?? It would be with other sa/ca cichlids. I just know that they grow pretty fast and a decent size tank is needed for them.

Tank size has nothing to do with how big it will get, if it is healthy, it will grow to full potential, and I agree with Seedubs, a 240 is a minimally proper tank for dovii. Any smaller than that, and it would be like you being in a jail cell.
If you go smaller, and have tank mates, their days will be numbered.
I'm often amazed at the reproductive instinct of Central American cichlids. 40g vs 600g, I guess there's a big difference between what you can get away with and what is ideal... http://youtu.be/Sy9APu9jE_E
*edit* not having a dig, obviously you're not suggesting a 40g is anywhere near adequate for a dovii.
to answer the original question of how big will a dovii get in a 210g? Bigger than it would get in a 40g, and not as big as it would get in a 600g+
IMO not having a suitable size tank to house your fish "available" is no excuse for not adequately housing a fish, unless it's under exceptional circumstances. If you've got a foot-long pair of dovii in a 40g tank I'd certainly hope you're planning on having something much larger available for them in the near future.
