in my freshwater tank, there's a big fish (> 2 inch, relative to other fish in my tank), it is heart-shaped parrot fish, previously I suspect it is fierce and kill other fish, so I isolate it in a container at a corner of the tank,
after months (perhaps even a year), it become starved(I feed sparsely), thin, tampered and non-aggressive, so I release it out, after a week or two, it accustomed to the tank environment again, and start moving gravels to clear out a volcano like area, it is it's usual habit, so I don't pay extra attention,
tonite I add more fish and look at the tank attentively, and discovered the big fish has laid egg at the bottom of volcano like area. The suprise is that most fishes find hidden, non-disturbing area to make their nest and lay their eggs,
but the volcano is made just in front side of the tank where I usually walk by.....
The other suprise is that there is no male parrot fish in the tank, (I don't know only 1 female will also lay eggs, like chicken)
I raise about 4-6 baby (< 1 inch) initially, this type of fish is fierce, when there is stress, it will kill others of same type, so at last only the biggest, well-fed one will survive, and today I know it's a matured female....previously I don't think fish will breed in my tank, because I keep many types of fishes, the traffic is busy and there is always a quarrel going on, so I never cater distinguishing their gender, except those fishes that differ obviously between male and female like peacocks
What will happen next? will the mother will eat up the eggs when they cannot hatch or when she get disturbed? (to get back the nutrient?)
I want to know, if there's male in the tank, will the father and mother will take care of the eggs together? when babies hatched and when there's danger(like other fish try to eat the babies), will the father catch and keep the baby in his mouth? Is parrot mouth-breed fish?
do you think I should buy a male of similar size? if the female do not like the new male, will I need to buy more than 1 male to let the female choose?
attached is an old photo where the fish isolated a year ago
another photo is whole tank view about a year ago, which is not valid now as I separate the tank in 2 partitions to keep more tempered fishes
