Fish Compatibility Checklist

Compatibility is about more than temperament. Tank size, water parameters, and feeding habits all matter.

Checklist

• Match temperature and pH preferences.
• Keep similar-sized fish together.
• Research fin-nipping or territorial behaviors.
• Ensure enough hiding spots and swim space.

Schooling Fish

Schooling species need groups of 5-6 or more to reduce stress. This affects tank size planning.

Bottom Dwellers

Choose peaceful bottom dwellers for community tanks. Provide soft substrate for species like corydoras.

Compatibility planning prevents stress, injury, and long-term issues.
