Gah, Cories!

[LyraGuppi]

I'm done with my ich treatment so I'm trying to lower the temp. I know hotter water can't hold as much O2. The cories are going up to the top for air, and naturally for the bettas and since I have sponge filters I don't have much water movement.
I'm running out of airstones, and the heater is not lowering the temp! What should I do about this?
Also, two barbels are broken in the tank! Will they grow back? Have I crippled the cories? I think it was on the piece of driftwood I put in. Should I take it out?

Was it a typo about wanting the heater to lower the temp of the tank? A heater wont make a tank cooler, the only way to acheive a cooler tank is to lower the thermostat on the heater. If you want to cool the tank quicker you could do a partail water change using cooler water but you will still need to lower the thrermostat on the heater.

As for the cory barbels as long as the water is clean and well maintained they should grow back.

Thank you for the quick answer.
 
I've been turning down the heater...is this right?

 

[Baccus]

Yes that is correct.
What temp was the thermomator set at prior to turning it down? While reducing the temp just make sure that you do it gradually to allow the fish a chance to readapt to the new temp range. changing temp to quickly can stress the fish and allow secondary diseases to take hold.

It started lowering as I was typing that. >.<

Thank you for answering my frantic thread.

Do a water change of slightly lower temp water and do it slowly... you don't want to cause temp shock.
 
 
also, what type of cories are they with the bettas?  

 

[LyraGuppi]

Okay, lowering the temp slowly at the mo.

They are albinos.

Unfortunately, the 'albino' distinction is shared by several species...
 
Primarily C. aeneus and C. paleatus...
 
The C. aeneus can handle slightly higher temps than the C. paleatus.  Both will 'survive' in the higher temps, but higher temps will lower their life expectancy because their metabolism is faster.
