I'm getting a new tank which will be around 40g and I'm trying to find the best algae eater: either bristlenose plec or oto. Right now I'm keeping swordtails, however, I'm thinking getting some bumblebee gobies which will need salt in their water. I've heard that BN's hate salt, but can't find any confirmation of that anywhere, so if someone knows the answer, I'd love to know. Also, can otos tolerate salt? The tap water which I use is medium hard and slightly alkaline, which is great for my swordtails; however, I'm pretty sure that catfish prefer soft acidic water. Will BN's or otos be really unhappy in this type of water? if so, does anyone know any better algae eaters for my tank?
