A PH Question
Today is the completion of my 3rd week of my fishless cycle. Not much else to do but read up on the hobby.
My question is; I would like to have Cardinal Tetras and Cory Catfish in my same 20 Gal L Tank. But this one book I am reading calls for a PH of 6 for the Cardinals and a PH of 7 for the Corys. How am I supposed to handle this? I know that Neon Tetras can handle a higher PH than Cardinals, but I don't want Neons. What do I have to do keep both species in the same tank.20 Gal L Currently Cycling.

Ideally, you shouldn't put fish with different pH requirements together. If the pH is only slightly different it isn't a big deal. You should match the fish to your pH, not the pH to your fish. Find fish that "fit" in your pH. Adjusting pH can be difficult to maintain and stressful on fish.
There are many different cory available, keep searching until you find one that has compatible pH needs and will fit comfortably in a 20g.
Seriously fish says cardinal tetra and panda cory have compatible pH requirements.

Brutal honesty will be shown on this screen.
I think my fish is adjusting well to the four gallon, He's laying on his side attempting to go to sleep on the bottom of the gravel.
Tolerance is a great thing to have, so is the ability to shut up.
I can explain it to you, but I can't understand it for you.

What is the pH of your water? And what is the pH of the water the fish store is keeping those fish in?
But, to answer your question, if both species are wild caught, you shouldn't try to keep them both in the same tank if you want to maintain your fish in the best condition you can.
Find out if the fish are wild caught or domestically bred - if they are domestic I wouldn't worry too much about pH, except to acclimatise the fish well when you add them to your tank.
ninja'd by mommy1...her advice is better than mine - find a more compatible species to fit your water conditions.

dont alter ph until you have a GH and KH test kit, TDS meter and a understanding how altering GH, KH, affects the ability to maintain PH.

My Neon's and Pleco has lived in 7.8 pH for 9 years and are doing just fine. The Neon's have been in 7.8 pH for almost a month and are very happy and shinny and swimming around in a group doing great. I only lost 2 in the very beginning and still have 23 of them.

Any of the captive bred cories as well as cardinals will be perfectly happy in water up to medium hard. So say a pH between 6 ad 7.5 will be fine
