Two honest caveats emerge from higher-trust sources. A high-trust r/Aquariums thread debates the presence of ethoxyquin, an antioxidant that some scientific commentary suggests can have negative effects at high levels—worth noting even though the thread itself pushes back on calling it a pesticide. Separately, an aquariumcoop.com forum user reported switching away from Xtreme because the pellets 'couldn't be chewed' and 'didn't sink,' though that complaint targeted the pellets rather than this flake. Combined with a notably high price, those points keep it just behind the leaders despite strong nutritional praise.

I have a community tank where all fish seem to prefer the tetra flakes ("Tetramint") over the other options I feed. I have 5 bettas, 10 guppies, ...
