Hey guys, I'm thinking about starting up a 20 or 30 gallon freshwater tank, as the topic title mentions. I'm really just in the planning stages at this point and I'm not entirely sure if I want to follow through with setting up a tank at all. I'll be trying to maintain a healthy and clean environment for my fish and that will be my main priority. I'm planning on under-stocking my tank by a significant amount in order to prevent any significant waste from building up. My initial plan was to purchase 5 or 6 corydoras catfish and maybe like 4 or 5 neon tetras and keep it at that for the amount of fish in the tank. Do you guys think that's an okay amount of fish for this size of tank? Or could I stock a lot more? Also, would it be a good idea to double up on the filtration system by purchasing two canister filters or something like that? I was thinking maybe putting a filter in the two back corners of the tank to make sure that the water is pristine. Would that just be overkill? Do you guys think it would create too strong of a current for the fish in the tank? I just want to keep the water as fresh as possible. Regardless of the filtration I plan on changing the water once a week no matter what. What do you guys think about this for a tank set up? Any input is much appreciated. Again, I'm just starting to plan it out, not set on anything yet, just in the gathering information stage.
