Turns out that shellfish is a Jewel Box Clam and it is very cool. Hard to convince students its siphon is not a giant mouth for eating chunks of fish. Questions about adding fish: Situation: Tank is stable and teeming with inverts, a few corals and one goby who came in on live rock. Since we are basically starting from scratch with fish do you suggest any certain order when adding fish, such as docile ones first? Preferable to add each one as we get it or several at once? Unsure how to select fish. Fish still in bag from distributor at LFS seems good so I can acclimate and skip LFS acclimation stress and brief stay there. However, in bag I cannot see if fish eats, swims well, etc., so not good. Used fish from existing tanks seems good to find ones suited to aquarium life, though should I automatically QT even if they look fine in their old tank? Been reading recent threads about Tank Transfer Method and ich treatment. So is the process the same for adding new fish who appear healthy and for ich treatment? I have never done full QT or encountered ich. Generally can multiple fish be in the same bucket without problems except for large adult fish, as someone mentioned in a different thread? While the fish are in the bucket for three days do they eat or do I do anything else? If I try to work around school being closed on weekends do you think I could start a bucket Fri evening and pretend it is Sat morning without 12 extra hours being a problem?
