Ok so I need to know just a few things about ngt datnoids because I plan on getting some. I've read that ngts don't get along with eachother but I plan on buying 3 small juveniles and raising them together. Would that be a problem or anything longterm? I do have some gouramis as dither fish in the aquarium. Also I want to know their growth rate on average. I'd be feeding a mix of silver side, fish fillets, and krill so a pretty varied diet (plus pellets if I can train them). On average how large is their maximum size and how long should it take to reach that? And the last question is at any point in their life do they need brackish water or are they fine in fresh?
