moray

1.020sg is already full-strength seawater, if you go for this salinity, then your filters will not be brackish anymore but will adapt to seawater-strength. I guess is that people who wrote 1.015 to 1.020 sg are assuming that you want to eventually keep the eel in seawater. Pure brackish is 1.010sg, so if you want high brackish then the range should be between 1.010 to 1.015 sg.

I will get back to you when I have more info about compatible fishes.

Actually, A friend just told me that dragon gobies could be kept successfully with various types of brackish and marine morays. However, as you might have guessed, the dragon goby is a brackish fish that is rare, and probably rather expensive. Plus it also has certain requirements of its own, so I can't say it's recommended.

I also heard that ropefishes (erpetoichtyes, a relative to bichirs) could tolerate low-end brackish water & won't bother your eels nor hogged all their food, but since you want to keep your eels in high-end brackish, maybe it's not so good idea to get a ropefish.

I'll search around to find another possibilities, so don't lose hope yet ;)
lucky for me, Drago goby is really common here. Almost every shop has them. I tried to have ropefish in brackish but it never worked out for me. I have 2 of them in freshwater now and they seem to do way beter.

ropefish can tolerate very low end brackish but it isn't recommended, however dragon gobies are extremely cheap here in the US and so common Walmart usually carries them. I've had 3 dragon gobies they are brackish but mine were kept in freshwater, they require sand and small food such as brine shrimp. They do get up to 24". They like hiding spots and either need to be the only of their kind or in groups of 3 or more. They are peaceful but slow to get food so no fast eaters

Glad to hear that dragon gobies are not so expensive in your country.

While in Goby mode, I think the Oxyleotris Marmorata goby (here known as Ikan Betutu) lives in the same brackish environment as G. Tile and E. Rhodochilus. It grows to 30-50 cm, not so aggressive (for a goby), and looks like miniature goliath grouper :D

Unfortunately, Indonesians consider these fishes as food, so, they are not so common in aquarium trade (more common in food fish market I'm afraid), so I have yet to find out how they would fare together with morays.

they are really cool. I remember seeing one kept in freshwater a few years ago. That would defenilty be a cool fish to keep with them. To bad u dont see them often. I will search for that fish. It is really an amazing fish. I loved how he stuck himself to the glass. :DIndeed looks like a grouper,
Ophiocara or butis butis

I've got 2 butis butis and they are fun to watch

Yes, it's a cool looking fish! :D but my initial re-inspection in local aquarium fish centers failed to yield any pet Marbled Goby yet. I remember I saw one just last year, a big guy of 35cm, but the seller said it was sold few months ago.

As I mentioned, here that particular fish is considered a delicacy, even scientists here are thinking the same. Glad they don't consider morays a delicacy as well..

im thinking about trying to ship one. But first I will try to catch something here in the wild. Most of our goby's will be cold water but there are some fish here that can live on 24C


I would like to buy such a cool fish as that goby u mentioned. but it gets quitte big and it will outgrow a 1,2m tank. I mean it gets around 40cm thats not really a good idea to keep in 1,2m

butis butis is probably food for the morays.
 
So I finally found 2 morays. The tank is ready to go only its still freshwater. The morays are 'swimming' happily in the tank. The tank needs to get a salt level of 1,5gram per liter.
How do I do this? do I add 20% brackish water every week? that has a saltiness of 1,5gram/liter
