I need a CUC that can reproduce!

[91yjeeper]

In freshwater, there’s a bunch of snails and shrimp that will reproduce according to available food supply. I.e. Malaysian trumpet snail and cherry shrimp. This is great because they self regulate the population and keep your tank clean.

Is there a saltwater equivalent?

Most of them take human interaction for them to reproduce. Some cerith snail are known to spawn by themselves

bristle worms, spaghetti worms, trochus snails, copepods, isopods,

Nerite, Trochus, Stomatella, Collinista, and Limpets, to name a few, are all snails known to reproduce in aquariums without intervention.

Amphipods, Dove snails, Mysis shrimp, Asterina starfish (if you really want to), Marine grass shrimp, Marine ostracods, some Sponges, and a massive variety of Brown, Green, and Red macroalgae (seaweeds).

Edit: Chitons as well

I’m considering asterina. Any downsides?

I wouldn't go with Asterina. They reproduce like rabbits and some are known to eat coral. There's alot of varieties and identification is very difficult. They are typically considered a pest.

Asterina starfish might also trample Coralline and other beneficial macroalgae varieties. If you do go ahead and decide to obtain them (which I would not), try purchasing them from a reputable source.
