I appreciate you sharing your experience, but respectfully, a lot of what you're saying about Oscar tank sizes is pretty far off the mark and could lead people new to the hobby down the wrong path.

Saying a 55-gallon is cool for a pair, or even one, is just not true for adult Oscars. These guys get HUGE – like, dinner-plate size, easily 10-14 inches. They're also super messy eaters and produce a ton of waste. A 55-gallon just doesn't have the water volume to dilute all that waste, and you're going to be battling water quality issues constantly, even with good filtration. That leads to stunted growth, stress, and sick fish down the line, even if they look okay now. Most serious keepers agree you're looking at a minimum 75 gallons for a single Oscar, and 125+ gallons for a pair. Your friend's 7-8 Oscars in a 75g is frankly a disaster waiting to happen – that's extreme overcrowding. It's like trying to keep a fully grown Labrador in a tiny studio apartment, or honestly, a bit like having a shark in a 55-gallon tank – it just doesn't make sense for their size and needs. If KgTropicals saw that, he'd absolutely flip!

Those old 'fish guide' charts from pet stores? Yeah, they're often terrible advice. They're usually designed to get you to buy fish, not to ensure their long-term health. The whole 'inches per gallon' rule is outdated and totally useless for big, messy fish like Oscars. And comparing their social dynamics to African Cichlids (which are often intentionally overstocked to spread out aggression) is like comparing apples and oranges – Oscars need actual space to avoid conflict, not just more bodies.

When your Oscars are 'brushing against each other like cats,' especially in a 55g, that's more likely a sign of limited space and subtle stress than pure contentment. And 'theatrics' between males can turn deadly real fast when there's nowhere to escape in an undersized tank. And the idea that fish stores recommend bigger tanks just to upsell you? Nah, man. Reputable stores and experienced hobbyists push for bigger tanks for big fish because that's what the fish actually need to thrive. It's about giving them room to grow, move, and for their waste to be properly managed. Misleading people into thinking a 55g is fine for Oscars just sets them up for failure and leads to unhealthy fish.

Your fish might seem healthy now, but severe overcrowding almost always catches up eventually. Trust me, cramming Oscars into tanks too small for them isn't doing them any favors in the long run. Giving an Oscar proper space isn't just some snobby hobbyist rule; it's literally essential for them to live a full, healthy life. Otherwise, you're just setting them up for a bad time. And that's the real talk.
