I have owned betta fish for 4 years now ... one last a year 1/2 red yet a blue one lasted only 5 months.... i now have a red and purple one that has lasted 2 years ad i just got a blue one a few months ago. I was wondering do the blue one really die faster? if so how can i be sure to keep by dom from getting sick *ps his name is domanic*..... and i hope your fish link is ok
