Setting up a cory tank
I wanted to set up a tank with only cories, how many are good for a plastic tank that is 24x18x12, can the water be 7 inches high i plan on using an internal filter[/list]

So a 22 gallon tank...but with the water less than half, that really leaves out teh number of cories you can add. Why would you only have 7" in a 18" tall tank? I would switch the filter out. That will not look very good.

If you raised the water level up to what it should be, then I would add 6-8 cories, or even 8-10 pygmy cories.

sorry i said the dimentions wrong its on a foot tall

Even at 12", why only 7" of water?

At that tank size, I would go with pgymy cories, and you could have 10-14 of them I would say.

The tank size would only be at 14 gallons, filled full, and at oly 7 inches, you get like 8 or 9 gallons. Falina, are you sure 10-14 pygmy's would be ok there?

i calculated it with a formula and it read to be 13 gallons and are plastic tubish things ok for fish?

Falina 03-03-2008 06:46 PM

Pygmies yes, normal cories definitely not. Althoguh I recommended that based on the tank being filled up, not at 7" high. Sorry I wasn't clearer.

PVC tubes?

Your tank is 14 gallons, filled up. With only 7 inches of water, you have 8 gallons.

Falina, thanks for clearing that up. I think 8-10 (I would do 6-8) would be good for 7" of water?

Falina 03-03-2008 06:55 PM

I would actually go with 8 even for just the 7g. Reason being that pygmies, more than the larger cories, tend to fade away when not in largeish groups. A group of 6 would be verging on too small for this species IMHO. They are not big waste producers and if water changes are done frequently and they are not overfed then water quality should not be an issue. Since it is height that is lost rather than floor space I don't feel that the numbers need be reduced quite so much as there is still space for them to move about which is why I am recommending 8.

I'm not sure what you mean by plastic tubes either. Could you explain/ Or maybe post a picture?

Here is the link of the picture of the tub:

this is the dimentions

24 inches long
18 inches wide
12 inches tall

it has a top so i was thinking of using an internal filter

and im sorry bu your calculations are all wrong if I was to fill it up only to the 7 inch march it would be about 13, i dont know how your getting about 7-9 gallons i used a formula online for sqaure inches to gallons
