Corydoras and betta

[ArtistGardener]

This subject has probably been discussed at length, but I want to set up a 20 gallon tank with mixed corydoras and a single male betta. AqAdvisor says it isn't advisable but . . . .

So, what are the chances for problems? Do I introduce the corys first then betta or other way around? I have never had a betta. My first thought was a 10 gallon betta only tank, but since I have an extra 20 and want to try a sand bottom tank for corys, I was hoping to combine them. Speak up all you experts! Also, if it is OK; how many corys are acceptable in a 20 high? I was thinking of four albinos that I already have and maybe another 8 of two different species.

Often cory's are the only fish more temperamental Betta's will tolerate. Honestly I would add them all together. Usually if there are enough plants with hiding places. While a 20 high will work a 20 long would have been better as there is a larger footprint for cory's. Due to the 20H having a smaller substrate area you should limit yourself to 6 cory's max IMO. Smaller species such as Panda's or Julii cory's would be a better choice.

Thanks, Rivercats. I picked up a 20 high on the curb (free!) along with a hood so plan to make use of it. I will be doing low-light plants only since it is a simple fluorescent hood, but I do plan to make it well-planted with wisteria, java moss, anubias, and java fern. I appreciate your advice and will just add a few of the smaller species of cory or stick with my four albinos.

I've got a 10 gallon planted. I put the female betta in first and a couple of weeks later added 4 albinos. My betta was curious about the new additions, but left them alone. She pretty much ignores them except at feeding time. When I drop the cory wafer, she'll go down & check it & maybe do a quick nibble. And then she goes on about her business. It's a nice happy tank.

females are a whole different animal than males though.

Every beta has a unique personality. I've had ones that are great in a community setting and don't bother any other fish whatsoever, and I've had ones that attack every moving thing. It really all depends on the beta.
