Hi all, are this species hard to keep. based from my uncs. experience out of the 40pcs shipped only 1 survived

Hi!

Well C. barbatus does not like warm T°, but really thrived in fresh water 21-23°c.
You also should not be keeping males together as these can fight to death.
Check Ian Fuller catfish of the month article about that fish!!!
Cheers

Thnx This is very good info!! tnx again!

I keep a group of seven with two males and already got five or six little ones from them. I have them in about 22°C and quite stormy waters...

hi,

I read somewhere that they can take max 18degrees celscius, some other places, 21-25degrees celscius.

can anyone advise about the temperature range for this sp? coz evidently looking at the previous two posts, they can thrive above 20degrees.

thanks!

I can only say, that two of six died last summer when the temperature in their tank reached 28°C. while I was in my holidays.

I believe, up to 24/25° could be the highest temperature for a few weeks.

24 -24 deg C is OK for short periods of time but 18 -20 C will maintain them in breeding condition. There are always exceptions to the rule and with all fish you cannot say what is exactly their requirement because nature just does not work to rules.

Ian

Ian, would you say Kronei should be kept at the same temperatures?
In your fish house with fan assisted heating, what sort of temperature range are you getting from top to bottom of the racks?

Tim

C. kronei are in the same temp. range but are a little more tolerant in warmer situations. The FH is, bottom, 66 - 68 F at the door end 70 F at the other and up to 78 on the top not counting the heated Hypancistrus tanks.

Ian

hi all,

thanks very much for your extremely informative posts. I suppose with everything there are exceptions to the rules, but then again, a guideline would be good for most I suppose.

I've got friends who are like dying to get them but I suppose with our temperatures of between 28 -32 degrees celscius here in singapore, it's a tough job to want to try and keep them. Chiller not withstanding. can't imagine if the chiller conks out though. woah.

anyway thanks a lot to all again. good stuff! I learnt something new here. Again!

cheers!

Ian,

Nice to see you the other day!

We would like to keep C. barbatus (or C. kronei), but in summer there's no way we can keep our tanks below 82 F. Assuming we would not be trying to breed C. barbatus, would they withstand (survive) this temperature?

Thanks,
Dinyar

If you can get some Kronei they should be OK, mine are at constant temp of 79f and seem to survive and thrive but not breed.

Dinyar,

It was good to meet you and Rustyas well. I would not risk C. barbatus at those temperatures, they will tolerate it in short doses but not for sustained periods.

The only way I could see it working is if you had a direct water drip feeding from the mains and that would need to be regulated with a thermostatic valvue. The water quality would also need to be spot on. This is something I may experiment with here in the summer because of the temperatures we have been getting in recent years.

Hi all

I often thought of the idea of running the water from my external pumps through some extra meters of wide hose placed in a small fridge/freezer.

Just drill an intlet and outlet in the freezer, and stop in some meters of hose.

Should i note, that i have free electricity

Anyone have expirience with something like this, or is the idea just to far out?

I don't know anything about refrigerators, but running your freezer this way sounds like it's going to damage it in the long run.

I was thinking along this line as well, when I wanted to aquire a old bar fridge to try out.... but too bad, not enuff time to go meddle with such stuff.... other alternatives... water cooler systems, refrigeration systems, etc, rip out the parts and use it to cool the water, best if done in a sump.

Anyone tried making such DIY chillers yet??

I've seen only one example where this guy taught that using a length of titanium tubing coiled to be placed within the sump for efficient heat transfer... and coils of tubing wthin the freezer compartment of the fridge to chill his tank.

Somebody should check my calculations, but I figure that you approximately need one standard size ice cube (~20mL) for every 2 gallons to cool 25 C water by one degree.

You can probably figure out how often you would need to add ice cubes if you knew the room temperature, surface area of tank, material properties (glass v. acryllic), etc. On second thought, that's probably better done empirically through a couple weeks of careful observation.

Just make sure the water in your ice is treated!

What a coincidence, I just bought 10 cory barbatus on Saturday! They are 1 1/2 " to 2" in length. Eating well and looking great. Now if I can just keep the temp down in the tanks where they are in. Temperature fluctuates between 70 & 75 degrees. I waited months for these to finally arrive and I am very pleased with the wait.
In about 4 months I have a good list of cories in my tanks:
10 - c. barbatus
8 - c. sterbai
8 - c. rabauti
5 - c. adolfo
5 - ehrhardti
4 - San Juan
5 - c. aeneus (albino)
Now to start breeding them! They are all in separate tanks.
