Deleatidium Posted April 27, 2002 Report Share Posted April 27, 2002 I am looking to have a school of around 20 neon tetras in my large (150L) tank. Around 2 weeks ago I got 8 neon tetras and placed them in my small tank (30L) for a quarintine period. After two days 3 more dead, and after a week only 3 remained. The ph is 7.1 and NO2 and NH4 0ppm and NO3 ~10ppm. All fine in my reckoning. The 30L tank has 3 resident female guppies at present and is quite brightly lit compared to my large tank and has been running for about 18 months. No disease was evident and all fish were feeding well. Can anyone offer any ideas why such a death rate would occur? My theory is that they didn't like the bright light and were overly stressed by the whole introduction. Quote Link to comment Share on other sites More sharing options...
Caryl Posted April 27, 2002 Report Share Posted April 27, 2002 Did they seem ok one minute then dead the next or did they exhibit some change in behaviour or something first? Quote Link to comment Share on other sites More sharing options...
Warren Posted April 27, 2002 Report Share Posted April 27, 2002 Hi Deleatidium, I cannot see why either. Your water looks good. If the fish did not die immediately (1-2 hours) then its probably not the water. What were they eating? I recently got some neons from a breeder in Auckland. I only lost 2 on the 5 hour trip home. Since then I don't seem to have lost any, allthough its a little hard to tell. I got 150 neons and they are in a 1200L tank. Its a little hard to count them all before they move! (They look great as a school - should have got 300 would have looked better). Neons do tent to be a bit temperamental when they are moved. They don't usually travel well. They need to be put into a really big bag with only a small amount of water (relative to the size of the bag). If the trip is longish (greater than 2 hours) you should use Oxygen to fill the bag. The bag should be laid down on its side in a chilly bin to maximise the water surface area. Once moved however they are usually ok. Maybe the shipment contained weak fish that would have died no matter who's tank they were put into. Have you checked the LFS to see if they were having trouble (if they will admit it).

Deleatidium Posted April 29, 2002 Author Report Share Posted April 29, 2002 Caryl, they didn't seem to change their behaviour. However I found them all in the morning so they died overnight so I may have not seen any change in behaviour. Warren, they were being fed high quality flake (Nutrafin MAX). They only spent 20 minutes in transit and I introduced them to the tank as per the slowly acclimatise method over a period of about 50 minutes. I haven't had time to go back to the LFS yet. I am in two minds as to wether I should get any more. I still want to have a school of neons in my large tank (150L). Yout tank, Warren sounds great. I think only having three neons defeats the purpose of having them. So I will ponder for awhile and see if these ones survive for at least a month.

Ira Posted April 30, 2002 Report Share Posted April 30, 2002 I'd suggest cardinals instead of neons if you can get them. They're a bit more expensive but they're bigger and a lot more colorful. I think they might be a bit tougher too. Quote Link to comment Share on other sites More sharing options...
