Talk:Pangasius hypophthalmus

They may grow to 1.2 m in the wild, but not in tanks. I had a pair in a 208 Litres (55 US G.) tank for a year with 3 big tin foil barbs, and they topped out around 8.9cm (3.5") or so. Huw Powell 22:20, 16 February 2011 (EST)

A store I used to visit had a 24" one that was growing fast, they custom built the owner a 8x4x4 tank for it. Your stunted one was in the minority, are you sure it was even a Pangasius? Pareutropius look like mini Pangasius. I've seen many big ones. My local store now has an 8ft show tank they often have "donated" monsters in. Occasionally there is a Pangasius, they just plain don't sell them as babies though. Most stores my way don't sell these fish at all any more, as they can't deal with the 2ft plus monsters they get back! --Cat 07:57, 17 February 2011 (EST)
No, they looked nothing like those pictures. They weren't "stunted", they just don't grow that fast in "normal" sized tanks. I have kept them several times, and the results were all the same. Actually, mine might have reached 5" over time. Give them a big tank, and a lot of time, and food, and of course you'll get monsters. But mine just got a bit of flake, FBS, etc. as needed, and the TFBs ate frozen (well, thawed) peas quite happily, so I could sustain their growth without creating monsters. As far as exact species, the key here is the term "iridescent shark", a common name. We may very well be talking different species, hence why common names suck. Perhaps the common name refers to different species across the pond? Huw Powell 22:21, 17 February 2011 (EST)
The Pangasius I've seen for sale in less reputable shops around my way have either been P.hypophthalmus or the even larger growing Pangasius sanitwongsei, or "high-fin iridescent shark" as it has a taller dorsal fin. But yes, most stores these days have realised that the internet and sites like Monster Fishkeepers actually mean people have realised the monsters they've considered or bought and they get returned, and they can't sell them on so they've stopped ordering them in! Haven't seen one in a store for about 2 years now. And that 24" one in that shop was only a year or two old. Tank size doesn't stunt fish! --Cat 08:15, 18 February 2011 (EST)
Perhaps not tank size, but nitrates do. One or the other. And I suspect the former is a big deal, since it helps with the latter. Huw Powell 23:06, 18 February 2011 (EST)
