Could I Get Away With Once A Month?

I'm going to university this fall, leaving an abusive household. the absolute most I can go home is once a month. is it possible to get away with a water change (as much water as possible, replacing filter media as needed) once a month. I would do up to 2/3 of the water, wipe down the sides, etc. he’s in a 20 gal.
if not, I will bring my black moor back to the store, but i’m really hoping that’s not necessary because it would create a lot of drama in my abusive household that i’m not equipped to deal with.

 

Yeah, but you would need a lot of plants and good light.

 

You would need water column feeding plants that grow faster than than they would get eaten.

 

I would either bring him with you or bring him to the store. Once a month water changes on a 20 gal with a heavy bioload goldie sounds like it'll cause health problems for the fish, and it sounds like you don't need more stress.

 

Floating plants like frog bit would be my go to if I was going to take a chance. Duck weed may also work. But in the long run you will be missing out on the daily routine and might find a fish that been dead for weeks. What is the point if not to ensure your pet does not live in an abusive environment?
