I was at my LFS today and they have ghost shrimp on sale for 35 cents each, now I was wondering if they would be good in a 5g to clean up the algae problem I'm having, and how many would be a ok # to get. Will they be ok in there with a betta??please any info ASAP would be greatly appreciated cause I would like to pick them up tomorrow, also if there is anything I should know about their living habits ie: what else do they need to eat, how do I adapt them to the water (is it the same as with fish), thanks in advance for any info.
