OK, I'm switching my question
I no longer have a TT eel, as with him going to be growing 3 feet long apparantly, and I would rather him go to a good home who can accurately take care of him...
However, I'm still on a quest to find an eel that can live or be acclimated to Brackish Water.
Now I'm researching (which I do before I buy any fish) about the Freshwater Snowflake Eel...
I hear these can be acclimated quite well, as they are a fish who does freshwater and marine enviroments.
Any thoughts? I'm looking for an eel that won't excede a foot or so, which these guys won't apparantly - max length in captivity seems to be stated as 6"-11".
The plan is for a Freshwater Snowflake Eel, and 3 dragon gobies to live in a 55gal tank - which appropriate rock and caves. I think this is certainly do-able for at least a while, as the gobies are small and young yet, and I would be buying a younger Freshwater Snowflake Eel.
Lemme know what you think.
