A dumb question but is it ok to keep a ghost shrimp in a betta tank??About 3/4 of a gallon big

If the betta is much larger in size than the ghost shrimp, he could eat the shrimp. If the betta were small and the ghost shrimp large, then the shrimp could eat him. Otherwise, they should be okay together. Both the betta and a shrimp would enjoy a larger tank though.

thanks!just two should be ok then
