Hi I was thinking about picking up a red texas cichlid. I have noticed that the larger ones fetch a nice price tag. Occasionally, I have come across juveniles that have not colored up yet that are only 25 - 50 bucks. My question is if i buy a smaller one do they tend to color up well or is this a fish you need to buy a well colored adult? Lastly, I was thinking about trying one in my 75 gallon with my rose queen. Is this a big enough set up or does it have to go in my 50 by itself? Thanks
