Yes Crystal Red, Crystal Black and Rili shrimp stay small only getting to around 4cm max. Rili shrimp are a certain colour morph of cherry shrimp Neocaridina. When you say blue shrimp I dont know which type your talking about but it could be bluebolts which again stay around the same size of the other dwarf shrimp.
If your just starting out with shrimp I would strongly recomend that you learn with cherry shrimp, they are much hardier, forgiving, cheaper and tolerant than some of the other types of shrimp such as the crystal shrimp.
