Fish Compatibility

[punkinmw]

I currently have about a 6 to 8 inch tiger oscar, a slightly smaller jack dempsey, about a 4 inch firemouth cichlid and a large common pleco in a 72 gallon tank. They all get along fine. My friend needs to get rid of a pair of parrot fish and was wondering if they would be compatible in my tank. I would love to have them if possible, but am not too familiar with them!

I doubt they would work in my other tank if this isn't a match, but here is the setup just in case!
55 gallon tank: 3 medium bala sharks, 1 silver tip shark, about 6 medium tiger barbs, 1 bristlenose pleco, 1 brown knife

Thanks for any help!

You will be needing a tank upgrade in a few months with the current stocking anyway so provided you upgrade sufficiently the tankmates can work together
