I have a beautiful Butterkoferi who is just about 4-5 inchs. The reason why i am selling him is because he is insanely agressive. If your looking for a nice agressive fish here it is. He can easily accomidate with bigger fish. I needed to take out my 8 inch oscar due to getting brutally abused. Also i needed to take out my 6 inch Green Terrer. Please make an offer if interested. Trying to sell as quick as possible. Thanks.
