What applies to tankmates also applies to conspecific. In fact, it's even more important.
No channa work in trio once maturity hits.
In fact, very little predatory fish do.
Either get a single specimen, either a pair (you don't choose a pair, they choose who to pair with, a female and a male very rarely make a pair if put together), or a group in very few cases.
Just asking again what if I mix few channa andrao and channa bleheri and channa sp assam in a 6 ft tank with lots of vegetation and drift woods with black water (for few months) as they are sub tropical ? I will add them at one go at winter time. What are your thoughts about this Madou and other mfkers ? Please reply. And thank you Madou for the info.
I honestly don't know, it "might" be enough room for them to be OK with it, skirmishes will happen for sure, but as for whether or not they'll be able to live long term... I would ask Devon's opinion, I don't want to throw you in a bad situation.
don't mix channa sp , and by the way channa Assam and andrao are same
, bleheri is more aggressive and bigger than andrao , they probably kill them , u must put in a group of bleheri in it
