About the Tailspot Blenny
Tailspot blennies are small reef fish that perch on rock and watch the aquarium between short swimming trips. They graze surfaces but should never be bought as a substitute for fixing an algae problem.
Their compact size suits smaller marine setups better than many blennies, provided the aquarium is mature and has enough food and cover.
Health risks to know about
Important concerns include starvation, jumping injuries, ammonia or nitrite poisoning, marine parasites, bacterial disease and conflict with other blennies.
A pinched belly, rapid weight loss, fading colour, rapid breathing, sores or refusing prepared food needs prompt attention.
Tank, water and equipment
Use a mature, fully cycled marine aquarium with a secure lid, small caves, stable rock grazing surfaces, open perches and moderate flow.
Measure salinity with a calibrated refractometer. Avoid adding another similar blenny unless the aquarium and territory plan can support both.
Food and feeding
Offer a complete marine herbivore or omnivore food, marine algae and suitable small meaty foods. Natural grazing alone may not be enough.
Watch the belly and feeding response rather than assuming visible algae means the fish is well fed.
Behaviour, tank mates and enrichment
Perching, grazing and backing into a favourite hole are normal. The fish may defend that hole from similar bottom dwellers.
Tailspot blennies are usually reef compatible, but a hungry individual may investigate fleshy corals or clam mantles.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
