Hi, I'm just a newbie fish keeper so would be good to get advice on what to add to my 120 litre tank. I've currently got 7 neon tetras, 1 blue gourami, 1 pearl gourami whom I think is female? Would like an opinion on this if I post a photo, 5 harlequin rasboras and 2 electric blue rams. Would also like to get an algae eater at some point. So what do you think peeps?
