There’s an ongoing debate among fishkeepers about whether Tetra’s SafeStart or API’s Quick Start even work.
First of all, let me point out that the “inch per gallon” rule does not apply for Glofish. Moreover, that rule is not and will never be correct for any species of fish. Imagine putting a 10-inch fish in a 20-inch (10 gallons) tank. With good filtration, It will probably survive, true, but will it be happy?
It’s understandable if you think that using glue around fish is a bad idea.
