Just so everyone’s aware, this is an AI generated photo.

It says so right under the picture, we are aware, but thank you!

Hardest part of having multiple tanks..............is getting permission to have more than one!

Nonsense, there's always a good excuse to have one more tank

For me having one than one would be a cost issue - double the dosing etc.

Unless the second was a more simple tank - like a Clown harem with Nems etc.
