i though the "one inch of fish per gallon" rule included shrimp, but someone said i coould have 3 ghost shrimp in my 1 gallon aquarium. ghost shrimp can grow up to 3 inches long, so that would be almost 9 inches of fish in the tank!
I believe it is more about the bio-load than total fish size. 3 ghost shrimp wouldn't create as much waste as a 9 inch fish (or 9 inches of fish) and seeing as they are scavengers they would assist in keeping the waste in the tank to a minimum. IMO 3 in a 1 gal tank would probably work fine.
ok thx for clearing that up. i was confused because if that rule applied to all fish, then that would mean i could have an oscar in a ten gallon, which obviously wouldnt work
tho you prolly could keep 3 in a one gallon tank i think one would be a better idea. i keep a cray and have been directed to a site ghost shrimp tho i was not directed straight to the ghost shrimp part. hmm according to that they grow to different lengths
well for a neon yea i would say its just about big enough possibly more if they are sick then it will do as sick fish tend not to be so active and hospital tanks tend not to have substrate or decor. and it would be short term.others would say its too small but i would use it as a hospital tank personally its infinately better than not having one.
