I have one betta in a 10 gallon tank. I'm having trouble deciding what type of corydora to get. Which one is my best option?
Corydoras Hastatus (dwarf catfish, tail spot pygmy catfish, some sites refer to them as "Dwarf corydoras, Pygmy corydoras")is the cutest corycat imo and I would try to hold out for them if they were compatible. They seem to be (incredibly cute) mid level swimmers. Does anyone have experience with Hastatus and bettas? They are so darn cute, but I'm not sure if they would work out well in a 10g tank.
Spot at base of tail:
Finally, there is Corydoras Pygmaeus. This may or may not be the cory that everyone refers to as the "pygmy cory." I'm confused because of the common names I have seen listed for the other cories. Is the actual Corydora Pygmaeus a better choice than Habrosus (Salt and Pepper Cory)?
Pygmaeus appears to have a well defined stripe:
I've found someone who sells Corydoras Habrosus (Salt and Pepper Cory) but I'm wondering how well it lives with betta fish? I'm thinking this will be the one but I wanted to see if it was worth searching some more and waiting to get a different kind.
Three black spots that may blend into a stripe:
Which cory do you guys prefer to keep with your bettas?
I have play sand in my tank. Will it be too rough? Will these little fishies uproot my plants? Will they help keep gasses from building up in my sand, the sand is 1.5-2 inches deep?
Could I have as many as 10 in a 10 gallon planted tank with my betta? Should I only get 6 or 8 of them instead? I'm hoping they can feel safe and secure.
