Behavior: The Canary Blenny will provide dazzling streaks and spots of yellow in your aquarium as it scoots from perch to perch looking for bits of food. Although the Canary Blenny is a mild mannered fish, it has a unique way of defending itself. It will bite its attacker on the mouth. The Canary Blenny is venomous and is not recommended for tanks admired closely by young children as it may bite a finger that goes into the water. The Midas Blenny is a better choice for an aquarium housed with children.
Canary Blennies are best kept singly unless a pair is housed in a larger reef of 80 gallons or more.
Feeding: Offer the Canary Blenny mysis shrimp, finely chopped meaty foods, and frozen or dried algae preparations.
Soaking all fish food (even algae) with vitamins will help keep your fish healthier and make them less susceptible to disease. We recommend soaking food in garlic as well when adding new fish and whenever your notice ich or other disease in the aquarium. Garlic will help repel external parasites and will boost the fishes immunity.
Feeding Tips: Remember to feed slowly. Leftover food will cause nitrates and phosphates to rise. If you see food falling to the sand bed and into the rocks, you should feed slower and give the fish a chance to eat before adding a little more. Using a turkey baster allows you to target food to different fish. For example you can feed the aggressive fish on one side of the tank and then squirt a little bit on the other side for the less aggressive fish. This way all the fish get a chance to eat enough.
Maximum Length: 5"
Care Level: Moderate
Reef Compatibility: Yes
Minimum Aquarium Size: 30 gal.
Range: Fiji, Tonga
Water Conditions: 75-80° F; sg 1.024-1.026 (1.025 is ideal); pH 8.1-8.4 Ca 420-440 ppm, Alk 8-9.5 dKH, Mg 1260-1350, Nitrates <10ppm, Phosphates, < .10ppm
Water Chemistry: Maintaining Ammonia at 0 ppm, Nitrites at 0 ppm, and Nitrates below 10ppm will help to keep your Canary Blenny happy and healthy. We recommend doing a water change soon after Nitrates rise above 10 ppm. Maintaining proper calcium (420-440 ppm), alkalinity (8-9.5 dkh - run it 7-8 if you are carbon dosing), and magnesium levels (1260-1350 ppm) will help to keep pH stable in the 8.1-8.4 range. We recommend a specific gravity of 1.024-1.026 with 1.025 being ideal for fish. Temperature should remain stable as well and should stay within a 2 degree range.
