Actually I did a trim just after the photo was taken
that is #4 for these guys It is so much easier in a smaller tank to do than a larger tank. Myaj was so correct when she mentioned that they should be limited to 3 or 4... after that it would be too difficult to distinguish who had a trim and who has not.
There's my fahaka, sorry for the the slightly graphic image, but this is her at around 10 inches after she took a sever dislike to a rainbow snakehead.... Oddly she loves the jag she lives with tho!
