ickle, birob makes an excellent betta tank. All you need to do is get a control vavle(like $1) for the air pump. And if you plan to replace the noisy air pump with a better one such as the whisper, most air pumps come with the control valve already. Then you can control the amount of surface agitation. Biorb is a good betta tank.
right i lost interest in this thread because everybody is slateing biorb's they are a genius step in fishkeeping for big community they are a no no but you could easily keep a little group of neons and a dwarf gourami in them i am buying a biorb for a dwarf puffer so the fact is biorbs are f#good for small fish but not big communitys
p.s before you slate things get your facts straight
how about you get your fact straight? only reason to get a biorb is for decor purpose. 6neon in a biorb is fine, 6 neon in a regular tank is much easier to maintain.
1) the entire view of the biorb is completely distorted due to the shape, you will never see your fish clearly, and it will be very difficult to even see the tank buttom.
2) the substrate they use means no bottom dwellers at all, only some shrimp.
3) cannot even be used as a hositpal tank due to the way the ugf is designed and the rough substrate
4) None of the standard aquatic equipments will work such as hob filters, feeders, etc. Need to buy biorb only accessories - much more expensive and limited selection.
5) Difficult to cycle, and you can very easily get into a mini (or major) recycle if ANYTHING is touched
6) Difficult to gravel vac
7) I feel sorry for your dwarf puffer
