Red Scooter Blenny: Everything There Is To Know About The Synchirous Stellatus

Despite being constantly referred to as the Scooter Blenny, the Synchirous Stellatus is actually, in fact, a member of the Dragonet family not the Bleniidae family (despite the name). Other names used for this fish are Red Scooter, Red Dragonet, Scooter Blenny, Starry Blenny, and Starry Dragonet.

These beautiful and vibrant fish originate from the rocky reefs of Japan, off the Southern coast. They are not only aesthetically glorious with their awesome patterns and array of bright colors, but they have big personalities and will provide an abundance of entertainment for all hobbyists.

The Red Scooter Blennies require a pre-established aquarium due to their unique feeding habits - they are not competitive eaters like most other fish. They will typically pick at rock-work for a lot of the day, providing themselves with entertainment and food at the same time. They are typically not distracted from what they are doing even if food is introduced to the tank.

Feeding Habits and Methods

The Red Scooter Blenny does need specific requirements when it comes to feeding them. They will spend the majority of their day picking away at rocks and the sand bed.

A large population of live copepods is essential for these fish. There are some that will also accept frozen foods, such as mysis and brine shrimp. It is worth seeing if they will take those foods, as feeding Scooter Blennies is very much a trial and error type of process.

They are carnivores, and so a varied, balanced diet consisting of copepods and meaty foods is a must. They are incredibly slow eaters and will certainly not be in any rush to the top of the tank when you begin feeding your community. They need the chance to stumble across the food when they are doing their usual daily activities, so make sure the rest of your tank isn't stealing their food.


The acclimatization process is very similar to other Blennies. You will place your fish in a bucket and drip acclimate for 1 hour (60 minutes) with a drip rate of 3 per second. This will then bring your fish's water parameters in line with the parameters of your tank.

Once your Red Scooter Blenny has been drip acclimated, you need to catch it with a net and place it gently into your tank. It is crucial when performing this process that you do not put any of the water the fish originally arrived in, into your tank.
