Is a dying starfish toxic?

[cwk84]

My starfish died yesterday. My fish seem fine but all my corals are extremely stressed. All of them including my RBTA. The water is also extremely murky. I heard that they release toxins when they're dying. Is that true?

I would do a couple large water changes over the next few days and temporarily add a big bag of carbon.

I'm already running carbon. 4 tbsp of ROX 0.8. Should I add more? It's only a 40g tank.

Depends on the type of starfish and its diet. If wild collected and was eating toxic sponges in the wild it very well could release built up sponge toxins. Poor example but more studied than starfish dart frogs can hold their prey’s toxin for many years after last feeding of toxic prey.

Running extra carbon temporarily won’t hurt

I did a 10g wc. Tomorrow I'll do another one.
