Lynda, no he’s in the same 5 gallon tank with the two shrimps and one snail. Other fish might be a problem but I’ve been talking to other Betta owners who keep them with tankmates and mostly, it works. Sometimes the Betta is too aggressive but, so far, Cherokee hasn’t bothered them. Of course, they are hiding anyway! 😀 Since I have lots of plants in the tank it works out. The shrimps are two males so no babies will show up; they would definitely be eaten!
