Wow really? Did you not see where I said "Guessing none of the fish are close to mature age"? You have fish that get to a potential large size. It has nothing to do with the fact that you have more than 2 fish in a 300 gallon. You didn't state sizes at all. Not a mind reader. If the fish were larger, it would be more of an issue.
I really don't appreciate the smartassedness. Wasn't rude to you at all, and asked valid questions pertaining to your topic. Don't see where the "monster guppy keeper" comment is coming from as I own some of the same fish (that's to you sandman).
Since you have a plan, then cool. But again I don't see how I'm supposed to assume that.
My RTC? I don't think this thread is about me, but I have stated my plans on other threads already. Don't think I need to explain myself just because I was going to try and help out.
Next time don't write "any advice is welcome."
On a lighter note, your filtration actually sounds very sufficient and I always like hearing about pothos as I am still growing out a lot of small shoots in my hobs.
I don't have any suggestions for your middle swimmers because I don't give advice on things I don't know much about, and the species you mentioned interest in fall in that category.
Next time please think twice before snapping back. Some people here are still genuinely trying to be graceful helpers.
