stomatelle vs. amphipods?

[brandoniscool]

I've had a number of stomatelle snails hatch in my 60 gallon tank cube. When the lights are off there is 20+ of different sizes crawling around. I've anecdotally noticed that I seem to have less amphipods on the rock work at night. I'm concerned that the growing stomatelle population is limiting the pod population. I have a green mandarin that has been flourishing due to my heavy amphipod numbers and I'm worried about him starving out. Do you think the stomatelle and amphipod compete with each other?

I doubt it. The dragonet is probably just running out of food already. They need alot of pods. My scooter blenny (basicly same thing..) is eating frozen mysis.. it's tricky but they can be trained into it down the road. IME. A refugium will also be a nice place for copepods to live and breed without being disturbed by predators so their larva may end up in the main display.

Nice reef! I'd put an glass top on it since kids will be very curious and may stick their fingers in the water with hand sanitizer or something or drop something in when no one is looking. Kids these days, I can picture myself wanting to touch the anemone as a third grader
