I know what you mean, they are a neat looking fish and very peaceful,in fact the ones i got as a pair were male and female and i had tried a product that claimed to disolve the gunk in the gravel and i tried it even though i do frequent water changes. well this stuff came from texas and must have been expose to heat because it poisoned my tank. ( petco refunded my money plus credited me for the fish i lost. lets cut to the chase, the little parrot was having a difficult time breathing and the other parrot kept with it nudging it so it would stay awake but it died. so i bought another and the bigger parrot adopted this one and protected it and showed it the ropes as they say. I don't agree with how they were made, but i had bought them before i knew. however, they are the stars of my 100 Gallon and they feed right out of my hand when i want to do that.
