Well one of my fish passed away, so half of my 5 gallon divided is empty. I have three options...
#1: Open it up and give the current fish all 5 gallons. This seems like the logical thing since 5 gallons is pretty small to divide. However, Tut seems really happy with his 2.5 gallons, and both my other fish are in 2.5 gallons. It would seem kinda unfair for him to have five... I know that's a weird thought
#2: Move my other male into the empty space, and get a new female for his tank. I don't want a male and female divided, because I feel it would be stressful.
#3: Get a third male for the space.
And just so ya know the 5 gallon was never meant for a divided tank. I was gifted a fish I didn't have room for, but the setup seemed to work after all.
