Dwarf or maybe Tropical Brittle Stars

Have a little nano tank 6.6G and had found one little tiny guy long time back, probably when I had the 12G, so a couple years.

Then after the tank move to the 6.6G, found there were 2, one with reddish color and one with more greyish purple bands (different colors so I knew 2 different ones).

Today I was looking for a baby RFA in the tank, last spotted in the middle a huge mass of Chaeto, removed the Chaeto into a bucket to see if it was still there, (nope) BUT there were at least 6 Dwarf or Tropical Brittle Stars, I was so shocked about it that I didn't keep counting them.

There was one living under a rock in the front of the tank which I always see its tentacles coming out to eat food particles, and maybe one which I have often seen move around under the stones in the outflow area ( two colors). So maybe 7-8 now???

And then there are 6 arms on this one and looks like the other pic, that one lost a couple segments, has 3 arms.

Are they reproducing, I guess?!?!?

Anyone have any experience about this or ???

Not sure if that is a common thing, but those little critters are amazing and I feel so blessed and happy to see them!

I do feed crushed micropearls and other things for the RFA's & little filter feeders like these.


Favorite tank right now - 12G Edge nano fish

New to FW fish? First tank in a long time or EVER??? Need some info on keeping fish?

These populations go up and down depending on how much food is in the water column. I had probably hundreds of dwarf ones in my 55 during my spike. Now I don't have one that I'm aware of.
