imagine 'fishville' game on facebook and you'll figure it out :-)
According to the stats that i've found, maintaining fish + water plant aquarium is the world second largest hobby after photography. The demand for 'aqua' related product or service is really high, both offline or online - and it steadily increasing. The problem is, every year there are estimated ten to twenty percent who quit this hobby - the main reason is aquarium always mossy, plants can't grow well, fish die without a known cause.
