After my success with Betta Albimarginata (to see journal: http://www.plantedtank.net/forums/fish/95608-phoenixs-betta-albimarginata.html) I decided to give my hand a try at Betta Macrostoma (meaning 'big mouth'). My local Fishkeepers Association had an ad up for six unsexed (I have noted that I have at least two males) juvi Macrostoma 2-3 inches. So I bit the bullet and bought them. They are now in my 45 gallon.
Things to note: Macros are FAMOUS for jumping. You must cover the whole top of the tank, if there is a one inch square opening they will find it. They will also hit plastic tops hard enough to pop them open, so it's best to use glass or weigh down the plastic top.
My plan is to grow these guys up until they can be sexed. If I get two pairs I will keep them and sell the other two no matter what sex they are. If I do not get two pairs I will look around the betta world to trade some males for females, or females for males. It would be best to do this anyway so I could get unrelated pairs and I might end up doing it anyway so I call get F1s and not F2s.
Here are my babies:
