Alright so I think I have finally decided how to set up my 29-gallon (upon "approval" from you guys of course.) I want to get four female bettas and six (or more) cories. A few questions. First off, is this going to work? If so, I remember hearing about hanging caves on some thread. What are these and should I get them? I already have one cave in the middle of my tank (sits on the bottom) but does each betta need her own cave? I'm also pretty heavily (fake) planted. But any suggestions on some real plants that bettas like that are easy to take care of? Also, I have light colored gravel (white and grey mostly)... any suggestions on some cories that would look good over this? And anything special that I should do for them? Finally, any other suggestions for fish that would go well with these guys would be appreciated.
