API Freshwater Master Test Kit

Keep ammonia, nitrite, and nitrate in check. Two-species tanks have more bioload and less margin for error than single-species setups.

Better pairings to consider

Discus do well with other peaceful cichlids, rams, or cardinal tetras. Tiger barbs do well with other barbs, larger tetras, or plecos in a separate tropical tank.
