A Fishy Problem: Contest Number Three

21 Feb

Here’s a puzzler for you:
Look at this tank. It’s a community tank of fish, with a bunch of fake plants, that I had set up several years ago. There are some very questionable things about this tank but can you name the single biggest problem that developed with this group of fish?

I have one particular thing in mind as the “Winner”.

There really are several possible problems so don’t be afraid to guess!
