^ i think that vid is just to show the aro eating live feeders TBH.
I still don't get the way some people think, the fish you buy should be the last thing you're thinking about. Everything else should be in place and running.
"I'm goning to get a bigger tank!" means you're going to have to figure out, filter, media, pump, plumbing, decor, lid, lights, diet, water chages (5gal buckets don't do it in 200Gal tanks) and anything else while you keep your fish in a tank that will be getting smaller and smaller as you get your new set up running. not to metion the cost involved of the new set up. There's also questions and problems you don't see coming until your "new tank" is being set up.
If you're loaded you can buy it all in one hit, but me, like most I presume, you have to buy completely new set ups in bits, tank stand and filter one month, filter media plumbing, test kits and pump the next, take a few weeks putting it together, cycle for a month, there's 3 months of growth for a fish that grows fast.
and your fish is getting bigger and bigger.
You don't buy furniture for a house while you're living at your mom's. You buy the funiture to fit your house when you buy the house. Backward thinking.
