kiwiraka Posted January 24, 2015 Report Share Posted January 24, 2015 I know it's been asked before, but just a few questions. Minimum tank size? Preferably for a trio, but I'm guessing even one would need a pretty big tank? Recommended turnover? Healthy diet? And how would you catch them? I went snorkelling with some some friends recently and there were schools of 30+ 2-3cm kahawai, a few of them were silver and yellow instead of the silver and brown colour of the rest. Do they grow up a different colour, or do they change as they get older? I'm guessing the temp would be the same as FW natives? Or would they need even colder?

livingart Posted January 24, 2015 Report Share Posted January 24, 2015 Kawhai need lots of swimming room and clean well oxygenated water can grow to 30cm in their first year lidded tank Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted January 24, 2015 Author Report Share Posted January 24, 2015 So would say a 6 foot by 3 by 2 be big enough? Or even bigger? Quote Link to comment Share on other sites More sharing options...
livingart Posted January 24, 2015 Report Share Posted January 24, 2015 They will get too big for that too, fish with turbo boost. As juvies they learn to live in a tank, mullet are a better option Quote Link to comment Share on other sites More sharing options...
Benjansss Posted January 24, 2015 Report Share Posted January 24, 2015 The way to catch them is with a good old fashioned rod and line and I belive they may need a round eged tank Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted January 24, 2015 Author Report Share Posted January 24, 2015 The way to catch them is with a good old fashioned rod and line and I belive they may need a round eged tank Lol, I was wondering if there was a more effective method, as I imagine target fishing for fish of that size would be extremely difficult. Would it be possible with a hand net? Or are they too fast? Would they really need a round edged tank, I thought only sharks, stingrays and jelly fish needed those.

livingart Posted January 24, 2015 Report Share Posted January 24, 2015 don't stick larger wild caught ones in a tank unless it is 1,000L plus they are 60kph fish in a short spurt Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted January 24, 2015 Author Report Share Posted January 24, 2015 I won't get one over 5cm, but if caught that small what size tank would be ideal? Quote Link to comment Share on other sites More sharing options...
SanityChelle Posted January 24, 2015 Report Share Posted January 24, 2015 It's not good practice to buy a tank for the size a fish is now. What are you going to do when it's bigger? Eat it? You can't put it back. Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted January 24, 2015 Author Report Share Posted January 24, 2015 Mmmmm, smoked kahawai !drool: What I mean is, if I caught a small one and it grew up adjusted to tank life, what size tank would it need? Quote Link to comment Share on other sites More sharing options...
livingart Posted January 24, 2015 Report Share Posted January 24, 2015 These fish can grow up to 75cm in length, weighing up to 9 kg, but their average size is 40-50cm and 1-2kg in weight. the one i have is 26cm, grown from 8mm to that size in 12 months, it is in a 1300L tank Quote Link to comment Share on other sites More sharing options...

kiwiraka Posted January 25, 2015 Author Report Share Posted January 25, 2015 Maybe I'll just have to set up a tank without kahawai. Oh well, I'll have awhile to think about it anyway. Quote Link to comment Share on other sites More sharing options...
