Im getting 20 new blue velvet shrimps, but my tank already has 3-4 orange sakura shrimps and 1 red rili. My concern is if they breed the offspring will have bad coloring. They are housed in a 25 gallon, I also have a 90 gallon but I house turtles and large goldfishes in there. I could feed them to my turtles but I feel like thats a big waste of money. Any suggestions?
