Yet another Cory question LOL!

Hey Guys

I have a 20 Gal tank with a male betta, and 8 tetras, 3 diff speices, I was wondering if I could put a school of 6 pygmy corys in my tank? My betta is very good with other fish, he seems to like them?

I was gonna let my tank run for a couple weeks, and then introduce some corys?

What do you guys think?

Don

Having never mixed Corydoras pygmaeus with a betta, I will leave it to the Betta specialists concerning compatibility. But if you do decide on pygmies, make sure the tank is well matured. If you have read a couple of recent threads on these fish you will note how sensitive they are to water parameters and quality. Like many others, I have lost them when introduced into newer tanks (within 2-3 months of setup), but never in tanks that have been running for several months and are biologically stable. A group of 6 (or more) is good. They do appreciate lots of plants, as they spend their days browsing over the surfaces of plant leaves, wood, rocks, much more than the substrate.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If youíre going to take it under your wing then youíre responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]

I have had regular corys with a male betta in a community tank with no problems but I have never had the pygmys. I don't think there would be a problem but like Byron said just make sure the tank has been running a while so you don't lose the cute little guys.

Kindest Regards,

Keeping fish its not a hobby it is a passion!

55 gallon, 44 gallon, one 20 gallon tank, three 10 gallon tanks, and a 2.5 gallon all with real plants.

I have MTS and there is no cure.

A happy, healthy betta needs a temp of 77-86F. According to planetcatfish.com, pygmy cories do best in water that is 71.6-78.8įF...I'm thinking that might make them incompatable in itself.As Byron said, these guys are fickle about water parameters. I lost 4 pygmies out of 6 myself recently. I suspect my water was too warm, too hard, pH too high, and the tank was too new. In fact, out of all the corrys I researched, only 2 fit my water parameters...Sterbai and Oiapoquensis. Most cories just like cool, soft, water.
