Fish Compatibility Checker

Check whether fish species are compatible before adding them to your tank.

Usage

Tell me which fish species you have or want, and I'll check compatibility.

Examples

• "Can I keep bettas with tetras?"
• "What fish go well with angelfish?"
• "Is my 20-gallon tank big enough for these fish?"

Guidelines

• Research every species before purchasing
• Consider adult size, not just current size
• Match water temperature and pH requirements
• Avoid mixing aggressive and peaceful species
• Don't overstock your tank, follow the inch-per-gallon rule
