| | Re: need help setting up my new tank 10 gal
A ten gallon tank would make a good size shrimp tank, the bio-wheel filter is however unnecessary if it will just be shrimp in the tank. It may be cheaper to get the tank alone and a sponge filter and air pump, or maybe not. I don't see the need for an air pump if you are running the bio-wheel. If you do run the bio-wheel just remember to use a sponge to cover the filter inlet if you don't want any babies to get sucked up.
The best, hardiest and easiest to find beginner shrimp would probably be red cherry shrimp or other neocaridina species like; blue pearls, yellow, snowball etc. IMO.
There really isn't a set minimum amount of each type you should get as that is up to you. You can fit plenty in a 10g and if you are wanting to breed them you will want to get 4-6 at least of each variety to ensure both sexes. Do remember many shrimp, like the ones I mentioned above can interbreed, which is not wanted.
They like an established tank with live plants and moss being preferable over fake ones. Gravel or sand works, sand seems to be a popular choice among shrimp keepers. It is nice to have structures for them, driftwood or rocks would work fine. Nothing really specific, but what you think looks good should be enough to provide them shelter if need be.
Hope this helps.
