Betta killing tetra, help

[barbmiester]

I went to a website that said you can put tetras and male betas together, so I got 6 then every day I got home one was dead next day another dead and my other tank has tiger barbs in it

When did you set the tank up? Did you cycle it? What kind of tetras are they?
What are your tank parameters?

 

[barbmiester]

They are neon tetras I cycled my tank
ammonia 0
nitrate 0
PH 7.6
73 degrees
but this is according to a strip
it's been 3 days since I got them and I acclimated them

Bettas are pretty territorial -- some individual bettas aren't, and some are. It's likely yours is territorial and doesn't like the tetras in the tank.

 

[barbmiester]

well what should I do

If your nitrates are 0ppm your tank isn't cycled. What is your nitrite level? How many tanks do you have? Your previous threads implied that you had barb(s) -in a 5 gallon tank, that you have a 30 gallon tank, and you have a saltwater tank? Now you have a betta in an uncycled 5 gallon tank? Why exactly do you think it is cycled? How did you cycle it? How long have you had the betta in there?

 

[barbmiester]

1 month and that is what my strip said and I also see big holes on the dead tetra

 

[Aegnis]

I think first you should try to see if you can return the neon tetras. They're going to be in danger as long as they're with the betta. It sounds like your tank isn't cycled either, which you'll need to deal with later.

[barbmiester]

I don't have I saltwater tank but I was wondering when I get one what fish to put in it and I upgraded my tiger barbs

I did it again and it says 30ppm

If you got the nitrate level wrong the first time, recheck the ammonia level again too.
What is your NITRITE level?

 

[barbmiester]

Nitrate 25
Nitrite 0.5
PH 7.5
Kh 40
Gu 40



That is not water problem and it’s skin is rated off

 

[Aegnis]

The tetra likely died from the betta killing it. You should see if you can return the neon tetras wherever you got them from.

Moving forward, it also sounds like your tank is not cycled, which means your betta is at risk of illness or death, so you'll need to do that as well.

Okay, your nitrites are a little high. That could be responsible for the death od the neon. They are extremely hard to keep alive even in well cycled tanks. If you suspect the betta of killing them, take them back to the fish store. The barbs will kill them too. What other choice do you have. There shouldn't be ANY other fish, especially schooling fish in a 5 gallon tank. You asked that before, and people advised you against putting schooling fish in a 5 gallon tank. If your betta is killing them, you made it easy for him to do that by cramming them in there with him. When fish die in a tank, other fish nibbling at the dead fish and decomposition start at the belly (soft tissue full of bacteria) that's most likely why the gut is gone first.

I just got a ten gallon for the beta

You will need to cycle it too.

thanks

thanks

I'm glad you got your betta a bigger tank! The best and safest way to cycle is without the fish in the tank. You'll need a bottle of pure ammonia (read the label-it should only contain ammonia and water) and a good test kit that tests pH, ammonia, nitrites and nitrates. The API Master test kit is the best for the price of any test kit in my opinion. I assume your 10 gallon tank came with a filter, heater and lid right?
