Good morning,
Congrats on the new 20g tank!
I highly recommend that you
not keep a Bloody Parrot (Blood Red Parrot) in a 20g tank. As fishingman001 has pointed out, the fish will outgrow this tank and become stunted if it isn't in a large enough home. Bloody Parrots are also large waste producers.
As for your comment in post #6 quoted below:
"All u people think that ever fish won't live it will for a long time."
we only want what is best for the fish, what is best for the fish will also be the best for you and your tank. Of course it's your tank and you can stock it with whatever you like. Whether or not you choose to listen to our advise is also up to you.
My largest Bloody Parrot is 9x6.5 inches and growing. I highly suggest having at least 2 Bloody Parrots and in no less than 55g for long term housing. These fish really enjoy the company of others of their own kind. As juveniles these fish frighten easily and the best comfort for them is a buddy of their own kind with lots of hiding places.
I hope you reconsider your stocking options and do what is best for the fish.
There are photos and a video of my Bloody Parrots in my profile if you care to take a look.
