Nervous because I am going away and dont have a good option to feed my 5 ember tetras and one assassin snail in my small planted low tech 2 gall tank (heated and filtered). Normally I only feed once every 2 days to keep the water from fouling too quickly. I have read a lot lately that I should be OK to leave them for a week provided I do a decent water change the day before leaving. But I'm nervous. Can anyone (with experience keeping embers) reassure me that they will not be dead of starvation after a week? They are so little! This is my first fish tank and first time away so I'm a bit nervous.
