Neon tetras dieing


Recommended Posts

I had heard that neon tetras have a bad habit of dieing for any reason or no reason.  I had hesitated to buy them because of that; however, the red/white/blue color appealed to my hubby. 

I bought a dozen two weeks ago. 

One died 24 hours after arriving in quarantine.

Last Thursday, I bought Cory's so I moved the tetras into the main tank (as first occupants) so the corys could have the quarantine tank. Main tank is a planted tank.

All seemed well. Until it wasn't.  Today, I found four dead tetras and one MIA tetra.

Water parameters: 0 ammonia, 0 nitrites, 20 nitrates, pH 6.5, kg 80, gh 75. Temp is 80 

I don't see spots indicating Ick.

Thoughts/ suggestions?

Not a lot to go on any loss of appetite what other fish are in the tank can you take a picture of the remaining neon tetra 

No noticable loss of appetite. No other occupantsIMG_20240701_193333234.jpg.ab6840571595bcb6199d5e7047555f33.jpgIMG_20240701_193451088.jpg.212c6ac6836b95c461ba3d0bf8dd004f.jpgIMG_20240701_193339371.jpg.8d1ec40de627fe328e387cfc5c532836.jpgIMG_20240701_193814739_HDR.jpg.b8cae2cd311a24f396e76c7b74750de4.jpgIMG_20240701_193455820.jpg.62a8b95e250c6175d8b87d015c305111.jpg

Where did you buy them? When it comes to neons, cardinals, or rummynose, I’d only buy from Dans fish. He’s nailed the quality for those species. They can be quite fragile when the quality lacks. 

PetSmart 

Yeah, not Smart...

Yep, as you get more and more into the hobby, you start to realize that if you factor cost of fish plus shipping, most times will still be cheaper with better quality in the long run. A $2 neon is cheaper than a $6 neon unless it keeps dying and you have to buy it 3-4 times in order to get lucky enough to keep it alive. In this case more may be more.

yeah, unfortunately that's the case. sometimes you need to buy twice as many as you want. if they survive the first three months, they're usually fine. I have given up.

I hope the last six survive but either way, I don't think I will get more. They are just too fragile.

I have gone with Green Neon Tetras myself from Aqua Huna and had good survivability of them.

I kind of like them for the smaller size and the occasional blue green flashes…

 

as I understand it they're more hardy than standard Neons….

They can all be hardy if sourced properly. If it’s petsmart/co or bust then I am of no use. 

PetSmart is the only source in town. Otherwise, I have to go up to the city to a LFS. That is where I bought the Cory's last week. (They are in the quarantine tank so not exposed to the tetras.)  If I go there for schooling fish to replace the neons, I probably won't get more neons.  They have some really cool schooling fish so for the money, I might as well up the cool factor. 😜

Not a lot to go on when you have  rapid die off that can be a fast moving bacterial infections you don't always get symptoms I would do a course of maracyn2 or kanaplex which ever one is more readily available @TinaPax-Peeks

Online is expensive though. If you can find a good local fish store that might be better. But keep in mind that they may import from the same source. Only so many places to import fish.

lfs is relative. I drive anywhere from 1 to 2 1/2 hours for local fish
