I find this post very odd, I can somewhat handle that your oscar doesnt tear up plants,
But too have like thirty tetras in their at all times without losing anything seems weird.
A oscar who hasnt been fed feeders before still have always ended up eating small things
with me, I dont consider oscars aggressive but instead this is a food source for them,
Do you keep him stuffed with pellets permanetely? How old is this oscar is it extremely old?
oscar is only about 3 years old. he gets fed NLS pellets like the rest of my fish once a day, at night before the night lights come on. like i said, i started with giant danios and he was unable to catch them. after about 6 months in the tank together, it appears he has given up on trying to catch smaller fish altogether.
