hello everyone

So I wanted some advice , have had my 20g tank for about 2 months now. Had a starfish (sand sifting) in my tank that I noticed was missing a limb one night to the next , and by the 3rd night he only had 2 limbs left.

I have a hawkish , 2 saltwater Millie’s and a hermit crab I got from beach . Could the hermit crab have killed the star fish v I have been feeding it pellets and it has been eating them but I’m afraid it has not been enough for the little guy.

I might just have to put him back in wild as I am scared he might want to catch one of my fish

Hello and welcome to Reef2reef.

What do you mean a hermit crab you got at the beach? Is it terrestrial or fully aquatic?

Putting a starfish (besides micro brittle stars) in a nano tank is never a good idea. It is an almost guaranteed death due to starvation.

They lose their limbs do to stress (in this case its likely its malnourished, and stressed from the crab), so I wouldn't expect it to survive in your tank. I would rehome the starfish.

Often when losing a leg, it can be high nitrate or phosphate and starvation in which your tank is way too clean for most any invert

But yes I’m such a noob that I got the starfish this early in
Moving forward, add no inverts until tank is at least a month old, better 2 months, No Anemones for 6 months and no stars for 3 moths. Snails can be added when there is presence of algae

It’s okay to be a noob. We’ve all been there at one point. Tiger conches are pretty cool and sift through the sand. Mine would eat those algae wafers when I felt like there wasn’t enough for him to sift. Maybe try one of those

This tank is cycled and doing great for a new setup. Missteps are common and a great way to learn as you go, ime.

Yeah, most true starfish (at least the reef-safe ones) are doomed to live short lives in our tanks at this point, with most I've seen (that survive beyond the first ~2 weeks) tending to only live ~8-13 months before (presumably) starving to death.

Sometimes large tanks can produce enough natural food for the stars to support them for a few years, but even with large tanks it's a gamble at best right now.

Usually, the first sign people catch that something is wrong is the star dropping limbs (though sometimes they don't drop any and just move on to the next step); from there, they basically disintegrate.

Personally, at this point, I'd recommend avoiding any true starfish other than some kinds of Aquilonastra ("Asterina") stars, which can reproduce fast enough to be considered pests by some people regardless (I personally like them though).

Brittle/Serpent Stars (Ophiuroids) are a much better choice at the moment, as these tend to do very well in our tanks - I would avoid the Green Serpent Star, Ophiarachna incrassata, however, as it's known to be predatory.

question i dont have any lights yet.
quickly realizing that even the small tanks are big monies.
what are the recommended lights for future coral
and will the light help me grow the algae.
more dumb questions to come.

im yet to do a water change because water parameters seem to stay stable due to the fact that its pretty new.
should i still be doing some type of water changes to get myself in the habit.

You can do one to 2x daily but other foods such as formula 1 frozen, LRS fish frenzy, TDO pellets, plankton and flakes
