Arrow Finally got a couple of cories!

I just bought two albino cories tonight. I know they should be kept in bigger groups than that. I'm trying to keep from spiking the ammonia again. In about a week or long enough to make sure my levels stay stable i will add more. I'm hoping the 20 will be done cycling by then and i can add them to it. They are currently in an over filtered 10 gallon. The smaller one is pretty calm, the other is constantly on the move, and fairly quickly. He tends to race around the tank, around the glass. Which one is acting normal? The tank has been lived in and constant tabs kept on the params so it shouldn't be that. I'm hoping it is just him adjusting to the new tank.

How long can two albino cories live in a 10 gallon? When will they be too big for it?

Why not use some of the filter material and or substrate along with some of the decorations from the 55 gal semi-aggressive,or 20 gal neon tank ,to help the other two tanks mature or cycle? Or are the tanks listed in your signature ,,tanks you are planning?

The most important medication in your fish medicine cabinet is.. Clean water.

I really need to change that, that's at least twice someone has went by that, oops. Those were tanks i was setting up, but then they got abandoned for different reasons. They're still more or less in the plans, i'm just setting them up one at a time. I'm running a 2nd filter in the 10 gallon trying to get it to where i can use the material for the 55 here soon. I suppose i could put some of the gravel in the 20 though. I don't know why i didn't think of that, i guess i just caught up in the excitement that it was getting fairly close to being done. I'll go edit my signature now, haha.

Cory behaviour...what you describe is perfectly normal. Cories do not like being moved to new quarters, and frequently will race up and down or back and forth across the glass wall(s) of a tank when first put in it; sometimes this lasts a couple of days, sometimes for several days and even a couple of weeks. I moved a group of corys from my 90g to my 70g and one of them behaved like this for 3-4 months, he's fine now (and had been before). They will (should) settle down, not to worry.

You can leave them in the 10g until the 20g is fully cycled (takes up to 8 weeks). They are sensitive to water conditions, so it is good not to add them to a new tank that is cycling. Once the 20g is settled, move them in, and add a couple more in a few days assuming your ammonia and nitrite are "0" which is where they should remain permanently. New fish should be added very gradually to a relatively new set-up so as not to crash the biological equilibrium. The bacteria will establish themselves in porportion to the available food (ammonia and nitrite respectively) and can multiply rapidly as the bioload is slowly increased. The larger the tank and the more established it is, the safer it is adding fish.

What other fish are in the 10g? Cories will never outgrow a 10g (I'd even say it's safe to put eight or so in there, so long as they're the only fish in the tank) so there are no worries there. As Byron said, it's better to make sure the tank they will be going in permanently is completely cycled and stable before adding the cories.

Thanks everyone. Sorry for the slow response. They both have settled in and look at home. They still swim wherever they please. THey are calmer now, though. They sift through the substrate looking for food like they should be.

iamntbatman, to answer your question, There are currently 4 tiger barbs (being moved over to the newly cycled 20 gallon fish by fish to not upset the balance. Then the two cories, as mentioned. So any breed of cory will live happily in a 10 gallon? I did not know that. I thought pygmys were the only kind you could keep in a 10. Good to know.

Now that i know they don't like being switched from tank to tank i'll just keep them in the 10 until i can get their real tank set up then i can move them straight there.

I would say any true corydoras species should be just fine in a 10g. The corydoras look-alike, Brochis splendens, gets a bit larger (over three inches and pretty plump) so they would need something bigger as adults. Pygmy cories are so small you could easily keep a group of them in something like a 5.5g tank.

sweet. I'll keep the cories in the 10 until i can move them over to their new (cycled) home. THat way i only have to move them once more. I thought they needed more room so i was going to move them to the newly cycled 20 then to the 20 long when i get it cycled. I'll just take them straight to the 20 long when it gets cycled then.
