when i got home today, the first i usually do is to look and observe my fishes for any improvements and other stuff.

i found out the 2 oscars ( whom i pressumed a pair ) laid eggs.

what i did, i removed the two fishes leaving the eggs alone.
what else do i do? i have a canister filter using a water pump.
should i turn it off and repalce it with a air filter?

how many days does oscar eggs hatch?
 
You should have left the parents with the fish - but now that you have removed them - take off the pump and use an air filter - a sponge filter is better, and keep a VERY GENTLE current moving across the eggs, and manually remove any white ones.
 
Should have left the parents with the eggs.
Now that theyre out I would remove the rock the eggs are on to a smaller container add an antifungal like methelene blue or something more modern and use an airstone to provide a gentle current across the eggs 2-3 50% waterchanges daily until the fry are swimming and can be put in a growout tank Good Luck!
 
Put the rock in a spare 10G or something and add the parents to the main tank. I doubt a sponge filter will filter a tank large enough to house 2 oscars.

Heres what I would do:
Add the oscars to the main tank.
Turn the filter back on.
Put the eggs in a spare tank with 2 sponge filters. (You'll need the extra one later)
Wait 3 days for the eggs to hatch.
Wait 3-5 days before they're free swimming.
Feed them Freshly hatched Baby Brine Shrimp as soon as they're free swimming.
You can also try feeding microworms and cyclops/daphina.
After 1 week, feed crushed up flakes.
 
there is one problem: i have placed a flat rock in the pond but the oscar laid the eggs on the floor of the tank.

this morning, i've seen seven or less red wrigglers. each has a head and with two identical dots which i presumed were eyes. is this possible that after laying, about 12 hours later, the eggs hatch? but majority of the eggs i saw were still opaque and still fresh. there are about 900 of them opaque eggs.

about the water pump, i deviced a sponge wrapped around the nozzle of the pump thick enough that it wont suck the eggs and the wrigglers i saw. for the soft current, can the drip of the filtered water from the pump suffice?
is this advisable?

i am worried that if i repalced the pump with a sponge filter, it wont handle the job as the pump does. i put methylene blue and antibacterial solution in the tank.

it has been more or less 12 hours since i saw the eggs. maybe after a day or two they will hatch.

need more suggestions for this...
 
BUMP!

it was the first spawn of my pair. as i have read from the sections of this forum, it is barely normal that the first will not be succesful.

there were many things that wrongly did:

1. I removed the pair. i should have left them off to fan the eggs.

2. I left the eggs in a tank rather bare and just letting the eggs hatch for 72 hours. I did not put an airstone to serve as the parents fanning effect. I relied on the current of the dripping water from my canister filter for this purpose, which was wrong.

3. I placed a flat rock and a piece of ceramic tille on its underside. But the oscars did not lay thier eggs on them. Probably i put the rocks too late.

4. I never did water changes. I thought that i wont change my water since the water is kept clean and crystal clear. this is because of a single reason, as an analogy: my filtering system was way too overkill. like putting a 1000 GPH inside a 75G.


what i need now are step by step procedures when my eggs are laid again. need specific steps and info. please try to base on my mistakes. need em right awayy.
thanks a lot!
 
i hate to say this. there were none. it was a total disaster, about 2 days, the eggs were all opaque but later after 3 days, some turned white until it spread althroughout. after 4 days, i saw 1 or two wrigglers. but i was frustrated so i returned the pair back in. after 6 hours, i saw the eggs were gone, probably eaten.

for this, i really need extra specific procedures.
