Long story short, my mum, on her way home, saw some fishes and decided to buy it. We bought a 5L tank and a water filter for the fishes and I think they are not comfortable as 5L is small for 2 pipefish, 2 clownfish, 3 other fish that i dont know the name, and a ribbon eel. Its just a few days after she bought them and all is going well except for the eel. He would not eat whatever we gave him. Then I thought maybe he wasn't feeling comfortable in the tank so we tried to separate him in a large water container to feed him there but he still wouldn't eat and I am getting really worried since I want him to live. We are planning to buy a larger tank if they survive for a week or so to avoid wasting money. Anyone have any tip they can share as to how they fed their eels for the first time since I really don't want them all to die...
