Why are they dieing!!!!!!!!!

[ScubaChick0121]

Hey so short story, I have a 20 gallon community tank with 15 nRon tetras a honey gourami, and 6 cories.... Well I had 6 cories but in the past month lost 5 of them have one left and he's looks ok.... Why are they dieing? Nothing else has died or is sick the water paramenters are perfect, temps stable, and once a week I have a 25% water change!!!!!

whats the water params?

Do you have a high concentration of aquarium salt in there? I know some catfish can't take too much salt.

 

[Sab_Fan]

were the cories well established, and then died all of a sudden? or were they new additions to the tank? you said all this happened in the last month, but how long had they been in there before that?

also, are you doing anything with plants, or CO2?

 

[ScubaChick0121]

I was moving around the sand and each week a Cory died.... I have had them for 8 months in this aquarium and I have no aquarium salt in

 

[ScubaChick0121]

Should I buy more cories for my loner?

Her fish's bioload doesn't even compare to more overstocked tanks. Her tank stocks are fine.

What species are your cories?

With you water changes are you cleaning the gravel each time. Iv found corys are very susceptible to infections from muck in the substrate
