Hey everyone, brand new to the site and soon to be fish owner, I just have a few questions... I have a 90 gallon fish tank which I bought for $500 and still have $300 left for some heaters, lights, food, test kits, pumps and all that good stuff. I was just wondering if it would be smart to buy some of the top of the line stuff for my fish, right now I'm still reading about the ammonia and the pH testing and stuff like that and would just like to get the right equipment. Also as for fish, right now I'm looking into Cory Catfish because they look to be good beginner fish and that's really all I have planned so far. tl;dr version - Should I get top of the line equipment as a beginner with a 90 gallon tank, and what freshwater fish would be good that are not aggressive for my tank. Sorry I'm totally new and lost, still reading up on everything so I'll be checking the thread regularly.
