We have 4 blood parrots in our 50 gallon tank. Apparently recently 2 of them felt so comfortable, that they decided to breed.
As far as we know, this species is sterile, so they cannot procreate. Is that true?
Well, anyways, they laid eggs over a rock in the corner of the tank and started guarding it day and night, biting other fish and me (very painful!) when i adjusted the plants with my hand.
Our black oscar was all stressed out and started having scales issues (skin hanging in spots, scales falling out) - we think it was because of constant biting by the parrot. These things bite!
After 2 weeks eventually the eggs went bad and were eaten. Our black oscar is ok now.
QUESTION: if they lay eggs again should we remove the rock and clean them off to prevent this aggressive behavior? Or will it stress out the parrots?
Anything else that can be done?
