I have one male betta fish in a one gallon fish tank with some java ferns that I hope to upgrade in the future (for now though, he has to stay in the 1 gallon. :( )
Anyway, I'll be gone for around a month on winter break, and I plan to give the fish and the tank to my friend to take care of. The thing is, I hope to give her the least amount of work necessary to take care of the fish. I was wondering if setting up a sponge filter will reduce the amount of water changes/ overall work needed? (I currently do a 50% change every three days, and a full water change around every two weeks.)
I'm also unsure of how to set it up. I'm thinking of buying something like the following: http://cgi.ebay.com/mini-Aquarium-Bi...#ht_5076wt_925
The tank I have him in came with an under gravel filter (which I don't use anymore since it generated a lot of bubbles and I don't mind water changes). Would the air tube and pump it comes with, along with the above sponge, be enough to set a filter up? How would I do it? Is it worth setting up?
Sorry for all the questions, and thanks in advance!
