Keyholes are nice. Picked up a pair not too long ago. Nice fish. Hard to sex though.All good suggestions for sure, keyholes have always been a favourite of mine too.
Next addition will be some corydoras i think, i am not in a rush at the moment to fill the tank so I will keep an eye out for anything interesting and see what inspires me.
I am having a lot of blackbeard algae and even a bit of blue green algae popping up which is a bit annoying.
