Are C. brachiatus predatory in nature at all. Reason asking- thinking of putting 12" one in 180 gal. which has a 5" Syn. polli in it. Do you foresee any problems?


Thanks,

I'm sure you will be fine but assume you are aware that both fish have very different requirements regarding water parameters.

I'm aware of the water parameters, thanks for the reply.

AFAIK no doradidae species are predatory - that is not to say a striped doras adult will ignore a neon at night, but they are certainly not piscivorous as in a RTC etc

Syno polli are tough enough & with dorsal & pectoral spines toward off anything they find offensive anyway

If you are aware of the waterparamerer issues then why still go through with this??

Centradoras needs water that is at least a HUNDRED times more acidic than Synodontis polli and vice versa

pH is a logarythmic scale, wich means that going from, say, 6 or so (a normal pH for any Amazonian catfish) to over 8 (Tanganyika) is to go from acidic to alcalic in a factor hundred.....

either way one or both fishes will suffer

just don't do this, period.

both species are also groupers. especially the Synodontis polli.
it makes a lot more sense converting the tank to either a Tanganyika setup or a South American one and buy more fish of the same species

otherwise it's just a very bad example of fishkeeping with only the greed of the fishkeeper in mind and not the welfare of the fish.
it should be reverse.
