Also. Just because of the fact that you have fairly hard water you can't be deterred from species such as Hastatus cories. They can do well in the higher areas of the water concerning PH and hardness, being able to thrive in a PH of 7.8 along with a maximum hardness of around 13 D. But the only note that I have about keeping these two species together would be that they do better in temperatures lower than a bettas prefered one. Hastatus Corydoras prefer a maximum of 78 while bettas prefer a minimum of 75 so meeting in the middle at about 76-77 or going the higher route to 78 could do well, but the Hastatus would much more prefer a temperature of around 74-75
Pygmies would be much of a better choice as they stay very small, and have a very small bio load compared the there bigger cousins. Even though they aren't as pretty, they are much more entertaining and will be seen in the mid layers of the tank. You could also have about 10 along with the Betta and 3 endlers
Alright. Well here is my plan..
1. Add the endlers.
2. Add Gilbert the betta.
3. Add new betta (in the 5 gal divided section of the 15gal).
4. Remove Gilbert for a bit, then add cories, put Gilbert back.
:D So I have some time, probably gonna go with pygmies though. I want the cories last since they need a better established tank.
Oh yea- that was what I was planning for originally anyways, haha.
I'm really annoyed, the LFS guy said "they don't know" when they'll get endlers in :(
I think I'll just get 3 males, they're smaller and I don't really want to deal with a ton of fry haha. Heard they are okay in all male groups unlike guppies.
Have you thought about wild guppies instead of endlers, wild guppies are much cheaper and sold under the name of feeder guppies commonly. They look practically the same, are just as active, and have the same requirements
