I have a 22z zero edge fully stocked I started with 2 red fire shrimp few weeks later saw two dots on my blue atlantic tang so I bought 2 cleaner shrimp even tho fire shrimp do the same thing as a cleaner lol ... But then I bought two more shrimp for my Qt tank and sins theres nothing in there any more I'm thinking about putting them in the tank with the other 4 ...... Is that to many? I don't think so be cause there great scavengers they eat all the brine shrimp that falls to the floor that the other fish don't eat ....but decide to post this to here what everyone thinks ... All the shrimp are about 1"
