A club for owners of Parrot Cichlids

Hello! I am a recent purchaser of my very first blood parrots.  The first is Calypso, who is a purple Jellybean. the second, is a adolescent blood parrot, by the name of Davy Jones. I bought Calyspo first because i felt bad that the other BP's were picking on it, plus my favorite color happens to be purple, so i bought it. I know almost nothing about BP's but because of what I learned on the internet, i now know that Calypso will probably die soon cuz it's a dye-injected fish. I hope it doesn't cuz Calypso is a really nice fish.

My first fish was a red tailed shark and he was lovely and lived to a grand old age of 17.  I then bought two parrot fish.

My shark and the smallest parrot fish died after my air filter pump stopped working one weekend whilst away but the biggest parrot fish survived which was touch n go for a while and he has now had a name change to Lucky. 

friends i have 4 parrots, 2 of them have big hump over the head, while other 2 didnot have any hump can any1 tell me what is the reason for this difference??

OK so i know i have been posting a lot og questions but i have a lot of them. So i am going to put more then one in this post. Here is the genral info...
5BPs-2 are 3-4inches and 3 are 2-3ish inches I have a 60 gallon tank. Yes i know i will need a bigger one i the future but they are not all thay big yet and there is plenty of room. I have 1 angel that is done growing and she is very small about medium to small sized both parents were small. I have 2 pleco, 1 clow louch, and a bottom feeder that i can't remember the name of. Oh and 2 rosey barbs.
