Hello I have had this Blenny for 3 weeks and cannot get it to eat. It’s starting to waste away. The fish is not showing any stress from aggression and no fish are picking on it. I’ve tried adding live pods/roe/calanus/LRS/ chroma boost TDO/ Vitalis pellets/ Nori.

Any recommendations would be appreciated.

Tough to see under blue lights, but it seems very thin. Fish don’t have good fat reserves, so 3 weeks without food may be too much for it to survive. Starving fish use their livers for energy, and that damage just isn’t repairable.

If you’re sure the tank is stable (if other fish and invertebrates are doing well) then the fault lies with the fish itself. It could have cyanide damage from collection, or some internal issue like a blockage.

Unlikely to work, but you could try live baby brine shrimp…..

I remember my Blenny ate rather small foods. Have you tried the small frozen fish eggs, to see whether you get any feeding response?
