My updated tanks:
Divided 10g with 4 females. yes I know I probably could have just done a sorority but I didnt have the money for tons of plants, and two of the females are pretty aggressive and I thought it would just be best to keep them seperated.
My 1.5g with spike he was in a 1g corner tank and so is loving his new digs
and my 5g which originally housed Kaname, but he is going to get set up in a newly divided 10g with little devil and two other future boys. This will now house my new King betta.
