I'm trying to start a colony in a 10 gallon I'm going to try supplementing my feeders...so, I have some Platy's in there right now as well... I only have one predator fish... so it wouldn't take much to supplement the feeders I'm buying... my thought on the shrimp, is Cherry's will be easy to see when added to the tank to be fed, & in my reading, the shrimp should really be culled to remove all but the brightest colors, to keep the colony bright, and not lose the vivid color... so I'm hoping to target the shrimp with poor color, to use as feeders, when or if I ever get to the point, that I'm netting a fish or two to go into the Bichir tank
