I have a two gallon fluval spec. I generally turn my light on while I'm gettting ready for work than turn it off until I get home from work. I turn it on and off when I go to sleep. I thought this was adequate for sushi and his plants but the aquarium store said the lights had to remain on for at least 8 hrs. Is he right?
In the tank there's one betta, sword fern, java fern and an Anubis.
Can you tell me the min/max requirements? Thanks!
