I'm trying to feed the tads some Spirulina, but am unfamiliar with it's usage. The capsules I have are full of blue green algae powder and spreads on top of and fouls the water. is there another form, like pellets ?
Spirulina is available in many commercially prepared fish flake foods. Buy the smallest size container available as it will take a long time to run out if you are just feeding tads. It took me about a year to run out of the smallest fish food container feeding a sixty gallon reef with four fish so it may well last you much longer than that. I'm not sure if there is an expiration date on fish flakes. Someone else will have to comment on that.
