Are they good?

[Veekoh]

Hey guys,

i just found those 3 guys that i’ve never seen before.
It’s been at least 3 months that nothing went in the tank because i was busy with school and my time for tank went south.

First 2 pics are, same guy, different angle (i think limpet).
Middle 3 pics are, same guys different angle (there are a bunch of them) | (i think either baby collonista, trochus or nerite).
Last pic, i have no clue!!!

Please tell them that they are good.
Thanks in advance.

1. Chiton. Not a snail (differentiated by the multiple plates on its back) but still a helpful algae grazer.
2. Collonista snails. Also good algae grazers that stay very small.
3. Not sure. Shell patterning and shape is similar to cerith snails like the Mexican cerith, but I think I can make out a large siphon extending in front of the snail, which is characteristic of dove snails (Columbellidae), alongside its two tentacles (though maybe it's just the angle of the picture). Both are usually beneficial grazers (I forgot that carnivorous dove snails existed until recently, but most that enter the trade are herbivores). Could you get more pictures of this one?

Hey,
Thanks for the first 2.

So little guy decided to hide in my top part.
He has two little antenna. But one trumpet that extends to run everywhere.
Has a long reddish shell.

My guess is a dove snail; the tentacles (antennae) of these snails are positioned pretty close together compared to those of cerith snails. Dove snails are incredibly diverse in color, patterning, and form, so it's hard to make an exact ID.
