What???
Buy floating pellet or pond food that floats.
Wait a few days and put in one piece.
See if they pick it apart.
If not, remove the piece before it gets
waterlogged and sinks to the bottom.
Quit overfeeding the fish.
It causes a rise in ammonia & nitrate levels,
and it makes it so you have to clean out the tank more often.
The more often you clean or do water changes,
the more likely you will inadvertently contaminate the tank,
causing poisoning, disease and death.
Feed the fish 3 or 4 times a week, (less for larger fish)
no more than they can consume in a 10 min. (5 min. for larger fish)
period, not leaving a single particle in view.
My larger fish, get a 25% water change every 4 to 6 months,
they have graduated up to "dog food" twice a week,
and if they don't eat the greasy chunks as I am dropping it in,
it is removed. (3, 10" red belly pacu's, 2, 8" green oscars & a 14" pleco.
The pleco gets half a zucchini once or twice a month.
And all of these guy's live in a 55 gallon tank with ONLY a
under gravel filter and power head WITHOUT a heater.
The younger ones are 11 years old.
FYI... Don't forget the Aquarium Sea Salt for your fresh water tank!!!
Anyone that says "what?" does not know what they are talking about.
It helps control nitrates and conditions the water.
