JenneyP Posted March 18, 2015 Report Share Posted March 18, 2015 i am looking at purchasing 3 Koura to put into a tank. is there any fish i can confidently keep in the same tank other than natives? was hoping to make a fresh water version of the sea critters i see when out scuba diving. looking at a 250ltr tank at this stage.

Benjansss Posted March 18, 2015 Report Share Posted March 18, 2015 If you're looking to make a mock marine you might like to know we also have freshwater shrimp crabs spoges tanaids and moss animals which are basically freshwater coral Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted March 18, 2015 Report Share Posted March 18, 2015 Koura need water temperatures of under 20°C so the only real non-native option would be goldfish which would inevitably have their fins nipped and torn while they're sleeping. They would also need to be bigger than the koura to stand a change of not being killed. If you go natives you could have smelt which are spend their life in saltwater but can be caught and kept for a couple of years when they come in to breed and bullies which are extremely similar to triplefins. And you could also catch some small grey mullet which can be good in a tank once they learn to eat flake food. Quote Link to comment Share on other sites More sharing options...
Benjansss Posted March 18, 2015 Report Share Posted March 18, 2015 Maybe mountain minnows Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted March 18, 2015 Report Share Posted March 18, 2015 Maybe mountain minnows Wouldn't recommend it, being diurnal and quite small, they probably wouldn't last very long. Quote Link to comment Share on other sites More sharing options...
Benjansss Posted March 18, 2015 Report Share Posted March 18, 2015 If the crayfish if big enough it won't be interested I haven't lost one mountain minnow in about two mouths there been in with the crayfish Quote Link to comment Share on other sites More sharing options...

Benjansss Posted March 18, 2015 Report Share Posted March 18, 2015 About the length of a large pencil not includeing claws Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted March 18, 2015 Report Share Posted March 18, 2015 About the length of a large pencil not includeing claws You've got a 20cm+ koura? I find that hard to believe. Quote Link to comment Share on other sites More sharing options...

kiwiraka Posted March 19, 2015 Report Share Posted March 19, 2015 The same stuff killed two commen bullies in the same tank Sounds like it would've been due to stress, probably heat related. What temp is the tank at? Quote Link to comment Share on other sites More sharing options...
Benjansss Posted March 19, 2015 Report Share Posted March 19, 2015 Room temp in the shadyest part of my room Quote Link to comment Share on other sites More sharing options...
kiwiraka Posted March 19, 2015 Report Share Posted March 19, 2015 Room temp in the shadyest part of my room And what temp would that be? Do you have a thermometer in your tank? Quote Link to comment Share on other sites More sharing options...
Ira Posted March 19, 2015 Report Share Posted March 19, 2015 Sounds like it would've been due to stress, probably heat related. What temp is the tank at? Room temp in the shadyest part of my room So, too hot for them then. You really need a chiller for natives, you can get away without most of the year, but that's not really ideal.
