I would like a quick select button in every tank which select another fish from the tank every time you tap it. tHis would display the fish specifications and when you then tap the isolation tank the selected fish would be isolated. Will be much easyer to select a fish when the tank is crowded.

I suggest also a 'continue to sell ' checkbox in the selling tank. This would give the possibility to continue the selling of fish while working in the other tanks.

Finaly a question: why does feeding not cost any money?

Great simulation!
