About a year ago I traded some plants for 6 juvie angelfish for my 135. They were about the size of a quarter when I got them. As they grew, they just started nibbling on some of my plants. Nothing major. Figured I would just add some veggies to thier meals. Still nibbled on the plants but I just let it go till a couple of weeks ago. They became so aggressive and went from nibbling to just plain destroying some plants. Guyana is gone. Decimated. Syng belem is so torn up as well as my stargrass and limno aromatica. Worked hard on my plants for them to do this. I had to net them all out and surrendered them to my local LFS. We loved those angels but me and the wife agreed they had to go.
