sand sifting star fish mating

[iamfrontosa]

One star fish sitting on top of another one. I did a search on google, and that's what I came up with.

The coolest thing I saw was when my hermit crab spawning.

Sand sifting stars are pseudocopulating, external fertilizers. They "mount" each other to get their gonads close together and increase the chances of fertilization, but they still release their gametes into the water to meet up

should i break them up? and toss one inside the sump? I don't want them to sour the tank.

I've seen them spawn before, but not on top of one another. Interesting. I'd split them up.
