Knife fish growth rate.

[nick.w]

How long will it take a BGK to get over 10inches??

 

[Eelzor]

It depends on water quality. With reasonably good water quality and decent feeding, I would say about 2 years.

Mine is about 11 inches now. He has grown about 5 inches in 4-5 months.

11 inches knife is best for fish
