Hippo, Yellow and Sailfin in a 150?

I think there is potential for that to go either way...could be ok, could be not so ok. I think Tyler hit that one on the head, that it will really depend on the individuals in your case. Although, as already kinda mentioned, both the Hippo and the Sailfin get really big. The 150 won't be big enough for the Sailfin, so plan to rehome when he gets large. The remaining two should be ok.

I had all 3 in a 120g for 8 months with no problems, however the hippo & sailfin did start to outgrow the 120g, so we did upgrade to a 230g.

IME the best is to add them together in the evening with the lights off.
For the first few days feed at both ends of the tank.
Make sure to feed them garlic extract soaked foods to ward of the possibility of ich, eh
Your tank has the length to accommodate them
