Tepid isnt warm enough. Bettas need a temperature of 76-82F degrees, which is acheived by having a heater. That tank, cute as it is, is much too small to heat. In cold water your betta's immune system shuts down and he will get sick with the likely possibility of death. He would really be happier in a larger tank, at least a gallon. In that size, it looks to be under a gallon for sure, so you need to be doing 100% water changes every other day, so harmful ammonia doesnt build up ;) Sorry to overwhelm you with info, but I just want the best for your fish :D
