Shrimp eating shrimp problems

The shrimp shouldn't kill each other. They are all simultaneous hermaphrodites so you don't have to worry about squabbling between sexes.

But they can be territorial..... I've seen video of two cleaners duking it out over territory......may have just been an odd situation tho as I've kept multiple cleaners before without any issues....

I just read the part where you say it's a 10 gallon tank...I didn't notice that on first read. That might be an issue then. 10 gallons is too small for one shrimp, putting two in there definitely could cause territory issues mostly because it isn't big enough for the lesser individual to escape.
