Neocardina fix?

[u/vamp-_-]

Long story short - we started a gundam shrimp tank in August before we left for university. We didn’t stock it because we wanted to let the tank cycle while we were gone.

Planning to stock it with neocaridina when we get home from school, but I’m wondering: will the shrimp be able to clean this up? There seems to still be a lot of biofilm despite online sources saying it’ll clear up on its own.

I also had a nerite snail - in an attempt to add some ammonia and keep the tank semi clean while I’m gone.

He has not been seen by my family in a long time (I’m thinking he climbed out somehow)

Any advice on how to clean the tank when I get back? Or would grazing shrimp eventually take care of it?

Thanks in advance!!!
