I blame it on the marketing of betta in a vase... The guy obviously "Hey, if it is ok to have a betta in a vase, why not in a wine bottle?"
Putting a betta fish in a wine bottle or a vase is wrong on so many levels.
1. The bottle is too small to have sufficient amount of water for stable water conditions such as water temperature, hardness, PH, etc.
2. The bottle has such small opening that there won't be enough surface contact for gas exchange.
3. The bottle is too small to have a heater and filter installed. Since betta fish is a tropical fish, no heater means certain death eventually. Yes, the fish might keep on living for a few months but that's the period of suffering lead to the eventual demise. These fish can live for years. Without a filter running 24/7, the toxic ammonia produced by the fish will build up and kill the fish.
Many marketing person do not know jack about fish or they simply do not care.
We always recommend minimal 5-gallon for a single betta fish. The tank also must have a heater and an aquarium filter.
