Trying to identify some things. I believe the green circle is a 'good' worm. Not sure of the name. It will come out and grab a piece of sand every once in a while. The blue circle looks like a feather duster to me. I did have a red sponge there but it ended up dying when my sg got a little high and I didn't notice in time. I travel quite a bit for my job. The Red circle looks like some type of algea... Good or bad?

I also have one of those little worms in the green circle, never caused any harm, but no idea what it is... In the blue circle is indeed a Feather Duster & the algae is green hair algae, which you need to get rid of as it will over take your tank. It grows when there is an abundance of phosphates in the water but I managed to get rid of mine by using some Rowa Phos & buying a Lawnmower Blenny

Default Bristle worm

That would be a bristle worm. Harmless, but unsightly, especially when they get huge. Don't ever touch them, their bristles are like glass and will prick you like cactus, and be very irritating since you won't be able to get them out easily. Nasty, but they are good as they eat all the leftovers. They used to be the scurge 15-20 years ago, but as people learned more about them, they finally decided they were good. You will always seem them at night. They sell traps if you want to get rid of them.
