You're probably not gonna like me but here goes, loose the gourami & the bala. Increase the Discus number to at least 5 asap. They are shoaling fish & are most comfortable in groups of 5 or more. Increasing the number will mitigate the single aggression. Bump that temp up to 82/83. Rams & angels will still be ok as long as temp & ph stay constant. There are a number of reputable breeders (some in Cali) that are just a FedEx away. My Discus came FedEx overnite to NY from Md. Simplydiscus.com has a number of sponsors with quality stock. But even if you choose to stay local, you'll increase your chances of success by following the above. Best of luck.
am I wrong in saying a 55g is not big enough for a bala?..
55g will work for the first few months but these brutes quickly grow to 35cm. They actually do best in groups of 3 or more but you're gonna need an eight ft. tank. "T"my post was clearly for OP not on your discus.
