Dixon1990 Posted March 10, 2008 Author Report Share Posted March 10, 2008 Haha thanks, What i really should have said was "What do you think the best Water Conditions for Cardinal Tetras are?" As all the different sites have different numbers like 21-28, 25-30, 22-26 etc. Quote Link to comment Share on other sites More sharing options...
MarkLB Posted March 10, 2008 Report Share Posted March 10, 2008 I've never kept them so I can't help from experience but it says in Dr. Axelrods Atlas '04........pH6, 22C Quote Link to comment Share on other sites More sharing options...

Faran Posted March 10, 2008 Report Share Posted March 10, 2008 My Cardinals are big and happy. They're kept in a 28C neutral pH tank with 30% water changes twice a week. MH lighting really sets off the colours, particularly the blue. Fed on colourbits and I hate to say the school of them impresses people more if not as much as the discus Quote Link to comment Share on other sites More sharing options...
DutchKiwiCowboy2 Posted March 10, 2008 Report Share Posted March 10, 2008 If I were to compare them to other fish from the same region (i.e. Amazon) I would put them in fairly acidic water. About pH 6.0-6.5 . Temperatures fluctuate in the natural environment but a good range would probably be about +/-26 degrees C. Fish will addapt to most conditions within a reasonable range of that but it is when you want them to breed that conditions have to be more favourable for them. Think about it. Amazon fish generally rely on the monsoon period for the young to survive. If they spawn too late the fry would have to survive during the dry season with less food in turn making them an easier meal for others because there is less water to hide in. The monsoon would lower the temperature of the water by a few degrees, hence the reason why some fish will spawn after a water change. There are many more of these types of situations that can affect the way you keep your fish, it just depends to what lengths you want to go to.

paekakboyz Posted March 10, 2008 Report Share Posted March 10, 2008 I've got a school of 25 @ 28c, 7pH, WC 20-30% weekly - mixed feeding (flakes, frozen bloodworms etc) and they are happy as. As Blue pointed out if you've got a healthy bunch and good lighting their colours look awesome! My Fav fish by quite a margin Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted March 10, 2008 Report Share Posted March 10, 2008 Rainwater with a bit of peat or oak leaves added (boil in a bit of water and add. Soft, acid and goodies-- like the creeks on the west coast of the SI. Quote Link to comment Share on other sites More sharing options...
new zealand discus man Posted March 11, 2008 Report Share Posted March 11, 2008 I breed them in 180 L tank thats 75% full of java moss all over drift wood { actually 500 year old Puri that died years ago in my place} it slowly rots giving the idea water..Just 100 % rain at 29 C I keep just around 10 as mixed M & F...The area has to be quite dark in the moss or eggs will die from the light.. Feed heaps of live BB shrimps into moss..Fry will hide there and come out when about 10mm..Never see before that..I have sold 200 this year..Breed here.. I have a black rubbish bag of the end..There ..A free tip..get breeding.. Se my notes about quarantine rooms.. :evil: Quote Link to comment Share on other sites More sharing options...
jayci Posted March 11, 2008 Report Share Posted March 11, 2008 I have a black rubbish bag of the end I don't understand the statement? Can you explain? Quote Link to comment Share on other sites More sharing options...
Faran Posted March 11, 2008 Report Share Posted March 11, 2008 Many tetra eggs and fry are photosensitive meaning that any light will kill them. He's talking about putting a black rubbish bag over the tank to black it out. For a very descriptive and informative article on breeding Cardinal Tetras, please visit the link to the FNZAS article below - Breed 500 or more Cardinal Tetras Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted March 11, 2008 Report Share Posted March 11, 2008 They don't need to be absolute blackout but very low light which means "no peeping" Quote Link to comment Share on other sites More sharing options...
