Hey guys I have a midas about 6inches? And a very small convict but I thought the midas would be more entertaining so some reason I do 2 WC every week and have to fluval 70s for filtration my water is 0 for both N and A is zero and ph is 7.6 I know kinda high but he just isn't very entertaining like I thought maybe after he matures he will become aggressive? Anybody know when that is thanks in advance
