Can Congo Tetra Live With Silver Dollar?
Yes, Congo Tetras and Silver Dollars do well together because both species share similar water preferences and occupy different zones, reducing competition.
Why
- Congo Tetras grow to 3 inches and stay in the middle water column, while Silver Dollars of 6 inches occupy the upper-mid zone.
- Temperature overlap of 73-82°F covers the comfortable range for both species.
- pH range of 6.0-7.5 is within the slightly acidic to neutral spectrum both species tolerate.
- Congo Tetras are schooling fish and prefer groups of 6 or more, which pairs well with the Silver Dollar schooling instinct.
- The 75-gallon minimum gives both schools plenty of swimming room without crowding.
What could go wrong
If tank decoration is sparse and open swimming space is limited, Congo Tetras may feel exposed near larger Silver Dollars, causing stress and color fading.
