Right now I'm about to set up my 90 gallon tank. The 'old fish' from my cramped 20 gallon are:
4 Yellow Labs
2 Red Zebra
3 Bumble Bee’s
What should I add? I'd like to have more popular fish that I could find at the LFS. And is 300 watts enough to heat a 90 gallon?

Oh, and do these guys have a high chance of hybridizing?

Yes the labs and zebras are famous for hybridizing. The crabros are very large and aggressive. If you are going to keep them, I would add to the existing groups and not add any other species. Six labs, five zebras 1m:4f and maybe 8 crabros 1m:7f to spread the aggression.

Yellow Labs and Red Zebras will hybridize quite readily, particularly if mates of the same species are unavailable. It would be a good idea to increase the numbers of the Zebras because a pair of these types of fish often turns into one, more numbers tend to spread out aggresion. so I think it would probably be best to add more of the same species if your not cocnerned about the Labs and Zebras crossing.

As far as the heater is concerned, it should say somewhere on the packaging what size aquarium it is rated for. If you no longer have the packaging you could try looking up the manufacturer's website for the information.

Though 300 watts is PROBABLY enough to heat a 90 gallon, I'd probably just get 2 200 watt heaters. That's what I have in my 75 gallon. There was something in the skeptical aquarist about heater size. I'd do a search on www.skepticalaquarist.com or something like that.

I'd get rid of either the esterae or labs. Personally, there isn't really too much of an upside to the estherae and I removed my group after a few months of them bullying my (much larger) dominant male crabro. You probably don't need 8 females/1 male, but I'd try to keep your female numbers up. Try some acei to school in the top of the (tall) tank, and you could probably go with 1 more species for a total of 4. Perhaps something blue would be nice. High quality callainos are beautiful, but I'm partial to Cyanorhabdos as well, they stay small for size variation, and they're interesting and colorful.
