29 gal tank

Question
I currently have :
1 zebra loach
1 burmese loach
2 kulli loaches
2 dwarf garamis
2 cherry barbs
I am interested in getting a school of fish... do I have enough room to do this and what would you sugg.  Do I have any more room after the school?  
Should I add snails to the tank?  i am not worried about over population because of the loaches.
Should I get any more loaches or bottom feeders?
Thank you!

Answer
No you do not need any more bottom feeders, you have a great assortment!!! You could add some more fish, although with the assortment you have you may want to try some Zebra Danios, they are small and stay small, like to school and very quick so your Cherry barbs couldn't pick on them to much. Barbs are also another good school fish however I have concern with a school of them your gouramis would get picked on to the point of dying. The zebra danios will get along with everything you have. Once you get the school of fish you want I would not add anymore. Best of luck and happy fish keeping!!
