So I'm about to acquire a 10ft long, 350g tank that I plan to stock with viejas, mainly melanura, zonatus and bifasciatas. My water is rock hard and I've been told they will thirve in it. I just wanted to ask for any suggestions/advice any experienced vieja keepers have, like what have you discovered with keeping vieja, perhaps breeding ease, feeding the right food, substrate/decor/plant prefferences, etc.
Thanks!
