Thanks for all your replies! I decided to get amano shrimp. :)
: I know it's better to have a mature tank before you add shrimp, because they are more sensitive to changes in the water. But I've been carefully been monitoring my water and it seems stable enough. I've kept brineshrimp and tadpole shrimp before so I have some idea what I can and can't get away with.
And to be honest, I just really wanted something in my tank and I am not able to get fish yet, so I figured that I will let the shrimp get in there first. Since there are quite a few brown leaves in there and some algae, and I do have algae wafers so can feed them.
My tank is quite planted. In the back I have some elodea and hornwort, on a piece of drifwood I have mini java fern, there's java moss on the rocks and I also have mini ludwigia in there, and a few fake plants around the filter. there are quite a few hiding spots.
I ended up getting five amano shrimp, because they seemed really cool and they grow a little larger which I like.
I've slowly let them adjust to my aquarium and as soon as I put them in they went exploring and eating, very fun to watch. But the last few hours they've spent polishing my piece of driftwood, all of them. And I wonder, does driftwood (I think it's mopani) have some kind of attraction to them?
