I also have a fire eel and tyre track eel together , but still fairly small 15-20 cm approx , and are happy as no hassels at moment , in 6 foot tank and share same hidey hole 8)
i would use marine salt :roll: , and a species only tank works best ,but mollies may be sweet , each gobie needs its own territory , and will not eat flake , pellets Lurves Blood worms , Mysis etc... (frozen or live )
Many other fish are in the same situation in there natural habitats ,being over fished , pollution and man made dams etc.., eg.celestial Danios , Red tail sharks , .., thank goodness for captive breeding
I just wondered why more havent been imported ,as like i said thousands are bred across Asia .
yes i do agree a breeding program here would be great ,but the breeder would also have to deal with certification , chipping etc...
