A bottle of pods
2 -3 times a week may cover you. These things eat a lot of pods
Lamaseta17 has a 100 gallon tank. I have a 125. Those tanks can breed enough pods
to sustain a dragonette. A 29 gallon can not unless you add a 50 gallon or larger refugium to it for breeding pods
. You also want diversity in the pod population. A bottle of tigger pods
alone is going to get very boring. You should look at getting a couple of differenent detrivore kits from different suorces.
Make sure it is eating prepared food before buying one.
