Your site looks good. Keep on posting and congratulations on such good idea. Far too many people believe that bettas don't need filtration or adequate tank space. They think of them as super fish and bettas are the ones who suffer for such ignorance.
I love it, Looks good, one thing to add, as a must, Is Water conditioner, other than a fish net, and in regards to the Worms, specify use only as a treat, not as a regular part of the staple diet. I would print it out, and bring it to Petco's and the like..
I fixed most of all the info expect for the spelling errors. I was focusing on the coding more then the info, since it just came off of the top of my head. Any info that anyone finds wrong that they can point out would be great! :D
