购买技巧

Cycle your tank first

Don't add fish until bacteria are established — wait at least 2-4 weeks.

Check compatibility

Some species are territorial. Research compatibility before mixing.

A hydrometer is essential

Check saltwater salinity (specific gravity 1.023-1.025) daily.

Prevent disease

Consider a UV sterilizer and quarantine tank for ich prevention.
