Puntius denisonii, sys.    10/25/12
Hello. Is it possible for this fish to live in brackish water with a specific gravity of 1.005?
<Mmm, this is too "salty" for this subtropical minnow for me... Will ask our brackish expert Neale for his input though. Most specimens of this barb are lost due to keeping it in too warm water in my experience though. Bob Fenner>|

<<For sure a bad idea. As Bob says, this subtropical barb is mistreated badly enough (read: short-lived) when kept in tropical freshwater aquaria, let alone brackish water systems. There are some truly brackish-tolerant barbs, Puntius Ticto for example, though these shouldn't be kept in anything other than very slightly brackish systems, around SG 1.002, 1.003.
As such, they'd be fine with Mollies, Glassfish, Knight Gobies, Spiny Eels, and other fish that prosper best with a little salt in the water. Cheers, Neale.>>
