Considered when the aquarium is running at full steam, just after assembly: filters on, lighting on as required (8h daily lighting? 10h? need to see which plants and fish you have chosen, to see what they need), CO2 introduced in the water, heater, in short, everything.

Sometimes particles can make the water cloudy for some time; the cycling period is also helpful to allow time for the particles to settle or be filtered out until the turbidity decreases. Above all of this, our attention should be focused on the good bacteria communities, which begin to fix and transform nitrogenous compounds into non-toxic forms.

Oscar fish is a favorite of breeders.

Its size and need for territory mean that each fish needs a lot of space. Start with 40-gallon breeder tank dimensions for the first Oscar and add an extra 40-gallon aquarium bill for each additional Oscar. If you’re a breeder looking to turn your tank into a community tank, you’ll need to pick some big, passive fish that will stay out of Oscar’s way while still being able to defend themselves. The ideal is to have only one Oscar fish (if it’s a relatively small tank or 40 gallons) or a group (for a large enough tank), then a hierarchy will form in the school, and there will be relative peace. But maintaining a group can create a problem in the medium-term if developing couples start fighting over territory. If the tank is not big enough, at least 40 gallons, you will need to separate those getting too much to avoid deaths. Oscar fish breed in captivity with some ease. When they form a couple, they will be together for life. The problem is that when this happens in community aquariums, the aggressiveness of these fish tends to increase and with the enormous risk of parents eating their offspring due to the stress caused by the simple presence of other fish in the aquarium. In these situations, the ideal is for the breeder to separate this couple into a tank just for them if they want to reproduce.

Only siphon the rocks from the tank if you want to remove any pests, such as algae, planarians, and cyanobacteria, etc. If dirt is on the substrate, you can siphon only the surface without touching the sand using a thin hose.
