Hey i noticed the other day i had a small small white starfish in the sand when i was adding some LR in and doing a little moving around.(Note: Tank is about 4 months old).Today i noticed 2 of them,both white,both small. Are theese good or bad? Should i worry about anything?

Asterinas. They're good.

Found them eating acros.

Are these small white brittlestars? (small disk, 5 or 6 thin arms) or a seastar (disk not obvious, arms blend in to it?)

Both come in a white color...both very common...both nearly always harmless.

The brittlestar for sure is a beneficial creature, reproduce well, highly desirable.

Asterina stars can, now and then be a problem, but this is quite rare considering the number of people who keep them. They may be accused of things that they are not responsible for as well.

Highly desirable, good at eating detritus. Will reproduce well in our systems. You have far more than two, I promise
