lol did you know fishes have a 6 second memory? lets say you have a castle and some fake sea weed in your tank. fish: wow a castle wooooww this is sooooo coool, omg sea weed wow this is soooo coool lets explore it. 6 seconds later.... WOW A CASTLE................ etc i think you get what im trying to say ^_^
I think, that if I ever start keeping fish again, I will most likely go with saltwater this time. Their absoluately beautiful with their vivid colors that and since salt water eat live bait, I can feed them feeder fish and watch them eat those, thats always fun to watch. However, I will probably also keep a smaller tank on the side as well so that I can have at least one Beta, as like I said, those are my absolute favorite fish.
