Oscar not growing

  • We are currently upgrading MFK. thanks! -neo
As a normal aquarists, we do not have the ability to directly test for growth inhibiting hormones..... but....
we can extrapolate their presence, with nitrate as a general indicator of generic nutrient buildup.
So if your tanks nitrate concentration is 20 ppm, you can assume that there is an equal concentration of growth inhibiting hormones that coincide.

If we do a 25 % water change, we are leaving 75 % of nitrate (and growth inhibitors) in the tank, and over the following week, our fish continue to add more.
So our next 25 % water change only removes less of that total than the first water change, and so on and so on over time.

Ok thankyou i got new fish keeper syndrome and got loads of fish but im thinking more practical now , i tried removing the jack but coudnt catch the bugger as with the unit underneath my tank it stands at nearly 6 ft, ordered a fish trap 🤣
 
My 2 cents. Need to maximize water changes. Stress never helps. My experience is that oscars like to be the dominant species in a tank. Other aggressive cichlids don't suit them. Smaller the tank the worse this is.
I don't think Ph has anything to do with growth rate.

Two nets. Use one to "herd" it into a corner then pin it in with both nets. Pretty much the only way to catch any cichlid is a two net system ;)
