Unexpected Cory death...

[PheonixKingZ]

Ok, thanks.

I will move the filter so the flow I against the back wall, going longways.

The two remaining Cory’s seem to be ok, so do the neons and the shrimp.

After the move, I will look into getting a power head or an extra internal filter.

Another one dead. Only one left. What can I do!? It seems the tank I have them in is a death house, but none of my other inhabitants are dying!

 

[FishGuest5123]

Gosh, I’m so sorry!

 

[PheonixKingZ]

Thanks. I don’t know what to do...

Should I keep him in that tank? Move him? Water change? What should I do?

 

[Byron]

Water changes are always beneficial whatever the issue, and cannot hurt. Make sure parameters are very close (GH, pH and temp) and this may help. Avoid treatments/medications until you know more exactly just what is the issue. I've no idea, so don't ask me.

 

[PheonixKingZ]

Will check the temperature right now and the pH. (I don’t have a GH test kit, but I posted what my water company says my GH is, on another thread)

I meant the parameters of the tap water being very close to those of the tank water, being OK for larger water changes. They are always beneficial no matter the issue.

Temperature is 78-80. Is that to high? I also have the neons...

What else is in the tank? That is too high for cories and for neons in the long term.

[8] Neon Tetras
[1] Panda Corydoras
[1] Albino BNP

Multiple Cherry shrimp, Nerite snail, BRH and MTS snails.

@seangee is 76F too high? What do you keep yours at?

 

[Byron]

Seangee will answer the question, but while I'm here on the temps mentioned, it was 78-80 and that is too high for neons and cories. My cory tank has been in the 24.5-25C (76-77F) range for over a decade. Now, this is the aquarium heater temp range which would run from autumn through to spring; summer heat waves increase the temp but not permanently, that is a very different thing (just so the OP keeps this in mind).

 

[seangee]

I'd probably run that tank at about 23C. If my arithmetic is correct that's around 73. I keep mine at 24 (75), but that's because I have cardinals with them and I have tougher species of cories.

 

[PheonixKingZ]

I will reduce the temperature a bit.

What is the long term affect of high temperatures?

Increased metabolism and shorter lives.
