I think you will be fine but I would go with either 2 x EBJD or 1 EBJD & 1 FM. I have no experience with Firemouth's but I've read they are mainly all talk. They flare and charge but rarely do damage. That said, since the EBJD is looking like the "main attraction" and is MUCH more expensive than the firemouth, I would get it first. Once the EBJD grows 2" - 2.5", get a small firemouth.
