I have a 3 gallon tank and I need something to help control algae. I'm thinking a cherry shrimp. it has one plant and a fake cave in it. do you have any suggestions?
A clean up crew is a good idea! I agree with @RussellTheShihTzu, one shrimp might not be able to make a big impact. Another reason for getting more shrimp is that they do better in groups. You will also need more plants for cover. It also depends on your betta. Some totally ignore the shrimp, but others may be aggressive and try to attack or eat them. Good luck!How long do you leave your lights on?
Better to get a Mystery Snail as a single shrimp won't make much of an impact. In addition, shrimp need lots of plant cover in house with a Betta.
