As you guys may or may not know i own a 2.5g it is pretty empty it has 2 ottos 2 guppy fry and maybe 5 tiny malaysian trumpet snails. there is a white crayfish at my lfs i would like to buy for this tank give me any information on keeping crayfish you have this will help me a lot.
Thxs guys, keep the fish tanks rollin
Get a smaller species instead, CPO's would be the best crayfish choice for such a tiny tank.
Cambarellus Patzcuarensis (var. Orange )
Sometimes called Mexican Dwarf Crayfish.
Another good choice would be the larger shrimp species from the Macrobrachium family. These are long arm clawed shrimp.
I had a blue cray. Same temprement as the white, I asked at my lfs. It would eat your ottos and guppy fry. The minimum size for a white cray is 10 gallons. I think that a dwarf orange is a better choice.
