i must have lucked out with these 2, i had originally bought 2 of them when they were little and one died when i added something to the tank and the product was bad from sitting in the sun on a loading dock in texas before being shipped to petco in nevada. it poisoned the water and the next morning i had some dead fish. 1 parrot was struggling at the top of the water and the other parrot kept nudging it to keep it moving and awake but it died. i had to do 2 water changes, filters and all. got the surviving fish back on track went to the store and had them check the product and yes, it was bad. they pulled it all off the shelf and they reimbursed me for fish, filter media and anything else i needed to get my tank healthy again. they gave me an armfull of stuff and said see what you can do with any of this.it wasn't there fault. i got the tank back on track and had a very lonely parrot that was sulking and missed his friend. so 2 weeks later i got another little parrot and the bigger parrot came out of it's slump, got it's color back and the 2 parrots are the best of friends and swim everywhere together.
