Seriously hair algae is the devil. You described my tank perfectly Its quite how I had it pictured in the mind's eye.. bit more hardscape is needed to give it some height. I have MTS in mine so they're probably clearing up most of any algae (other than the damn hair stuff). So yeh, the Otos would need to be house trained
I need to pay more attention to my cherry shrimp. They're doing well and ive noticed one or two with eggs, or 'berried' as ive heard you mention. But, ive no idea how many I have, or how many females..
Lol, hope I don't sound like a creepy nut. I'm stalking your fishtank!
It was only the other day that I saw the photo you shared. I remember it pretty clearly because I liked it so much. I'd like some valls, but they get a bit too tall for a 15 gallon really. Hmm, I could stick some in my dad's 55 gal, but he's covered the light to make it dimmer, and only java ferns and moss can survive. Might have to fix that.
I have no idea how many female RCS I have either. Trying to keep track of that would drive you insane! I just happened to spot a berried female
