I am currently about to upgrade with a 90 Gallon tank I am going to purchase off of Craigslist for a great price. The Tank comes with a 404 fluval filter, is that adequate for 90 Gallons? I am going to start the two week Ncycle and was wondering if I should purchase live planted plants from my local fish store to add during the cycle or should I plant seeds in there? I was also wondering what fish I could introduce into my tank? I currently have: 2 Large angels, 1 Common Pleco, 2 Dwarf gouramaris, and 5 green barbs. I was thinking 2 yellow parrots, I know they're aggressive but with all that space I would think they would be fine. I was also going to buy some apple snails but wasn't sure what to look for to make sure that they aren't carrying any harmful bacteria. Would I be able to add the snails during the N cycle?
