Thanks for the comments.
The danios could be feeders but nothing goes after them. I always hated giant danios but am starting to like then for the way they are always moving. I have them in two 120s for dithers. Damn things keep spawning.
Johannas are considered one of the less colorful pikes but you couldn't prove it by her. I think part of it is because many people haven't seen a female the size of her that has been fed on fresh shrimp, FD krill, tilapia and a variety of pellets. She gets fed every other day for the last year.
I may sign her up for weight watchers and look into a gym for fish.
