After I saw yesterday an auction at AB with Sineleotris saccharae, I think it's time, to tell a bit about these beautiful but also very sensitive Sleeper Gobies.

As I wrote in another topic, got my importer 80 animals from China. He told me there were 300 been caught, but it died 220 on the way to the exporter. The great dying then went with him on and in the end would only have 7 animals survive, which he then sent to me.

Also, I found no information on the housing conditions, and so I had to experiment a bit. First, after a bacterial sensitivity of the animals, I transposed it quickly in an aquarium, which I previously had been completely sanitized. But the infection immediately snatched away a first animal by the arrival.

The water levels seem to play a crucial role in the gobies. First I took the conductance with standard hardness salt to almost 800 µS and they were somewhat calmer. Yet still two animals died, which were already weakened arrived. After the death of the second animal I put everything on one card, and used the 7.5-Sulawesi salt, whereby the pH is brought relatively stable at just under 8, but the conductance remains at about 540. Since the animals are very stable. Temperature at 22 - 24° C.

The distinction between the sexes was difficult at first, because the animals were very hidden. I got to see only individually, so a comparison was hardly possible.

Meanwhile, the four animals living on 110 x 50 cm and have each staked out their territory. Since then, I see them sometimes together. One female living always hidden, because the other female is very territorial. The second female has the final say in the tank :-) The females have shorter dorsal fins, a short, round head and get after some time with good food a rather rotund belly.
The males have a narrow, long covered head, longer dorsales, are more slender and quite restrained in the females. These can be very aggressive towards the males.

They eat a lot and gladly. Most live foods such as bloodworms, Tubifex and white worms, as well as frozen food. They eat willingly shrimp, mysis, brine shrimp (adult) and all other larger varieties frozen food.

The aquarium must be well structured so that individual animals can pull behind a privacy back, otherwise there is constant fighting. They are very solitary, but in between looking after the fellows sometimes :-)

Especially important is hygiene, hygiene and hygiene. They are very sensitive to high pollutant concentration and fluctuations in water levels.

I am now waiting for the first offspring :-)

Interesting! But transportation of fishes in general is in my opinion largely inappropriate. Is it worth so much death?

Is not this species at home in Hong Kong?

Thanks Jutta! Beautiful fish. Do you think these are generally very sensitive, or was this particular batch poorly treated? Is there a paper available? Good luck with the spawn. Maybe f1s will be better suited to aquarium life.

Jim, unfortunately there is no paper. Because there are about the animals also otherwise almost no informations, I do not know whether their constitution was bad at catcher and in the bad conditions that offer the catchers of the animals often. But their sensitivity is also continued now that they are in good condition. If times from a water change or fluctuations in water levels are too high when moving, they are instantly grumpily.

Bojan, no, it doesn't worth, I think. It hurts, when I see them on a stock. They are very lovely, but for a handful beautyful fishes so much dead animals? No!

And yes, they are from Hong Kong.

Awesome fish. Sad to hear that they are so sensitive to transport, but it seems that the few that made it are in the right hands. Good luck!

Some fish are just not suited for the trade. Unfortunately, money is too often the only concern.

Really great post Jutta, thanks a lot and best of luck with the remaining ones. I've a couple of friends in Hong Kong so will ask about this fish for you.

Yesterday I raised the temperature a bit, to about 26 ° C. The result is that all four gobies appear in the most beautiful festive dresses :-)

The dominant female makes over and over again up to my disheveled Male ... and chases him away in front of the camera! Evil woman!

Let's see if the higher temperature brings the ladys and gentlemen in motion :-)

 

This male is a little bit shy, because the other male attacked him constantly....

and so he looks, if he sees the little male :-)

Very nice Jutta. Fingers crossed for the ensuing romance.

Looking great Jutta, how physically aggressive is the dominant male?

Also, I've been meaning to ask if it would be ok to use some of your photos for species profiles? Am planning to update the goby and eleotrid species sections shortly and your accounts and pics would be an invaluable inclusion. *prays*

The aggression is still limited, Matt. It remains in principle previously used only for hunting and there will be no really violent, physical attacks. However, the basin is also quite large and very well structured, so that they can avoid each other. I would imagine that if they could not escape, really hurt each other, because they mean this threat and scare very seriously.

As for your question, Matt: yes, of course you are allowed to use my pictures, my texts too, if you want. I am writing here in the forum for the community and I am very keen that this information be passed :-)

Very interesting....

Please forgive me if I'm making a mistake here, but I wonder about the proper water these chaps need... they seem to come from Hong Kong sensu stricto, New Territories mentioned on Fishbase... quite likely from an estuarine area, and thus brackish?  This agrees with you keeping them successfully by adding regular or I guess lake salt (Sulawesi 7.5?)... but then is it possible that high losses during shipping may be explainable by exporters keeping them in fresh water (cf. what happens to Knight gobies all the time)... and further, perhaps what they will like best would be something like Instant Ocean?

(Yeah, I have been looking at the AB listing too Embarassed beautiful fish... hope you succeed with them!)

No, Mike, Sulawesi-Salt is not a sea-salt, only specified minerals, which are matched to the minerals in Lake Matano in Sulawesi.

I do not think this is a kind of brackish water fish. That they are so sensitive, may be because my tap water is very low in minerals and has a very low conductance. However, they have on the mineral salt from Sera also not responded very well. It seems they need a certain composition of the water in order to really feel comfortable.

Jutta that is fantastic news and very kind, will make sure full credit is given. Thank you! :)

If I remember correctly Matano has particularly high concentrations of iron so presumably that 'Sulawesi salt' does too?

Looking at the price per kilo it contains unicorn tears.

Matt, I know the exact composition not and I have not yet measured, for example, whether it Iron increases. Shrimp Roy (Roland Lueck), the developer of the salt reveals of course not the composition :-)

However, I have already noted in the Sulawesi gobies and Tylomelania that the animals are excellent in this salt. The larvae survive in it much better than in normal mineral salt.

Yes, it's expensive! But one needs only 3.5 grams per 10 liters.

Quite possibly...there is also a similarity to lh.disparis -- it is also a Hong Kong fish and exhibits similar horrendous survival record with imports. For example, I picked up 7 healthy looking imports at a store last fall, one survived, and this is typical.---I've been through this many times. Now, it seems not possible to keep them in soft water (NY tap, TDS=40), but already at 150 (via Kent Marine RO right salt) they do fine and breed too. Anyway.. here is one thing you can do: write to Hong Kong water department, contact given here and ask if they have applicable water reports. One can also ask Anthony (Wetspot) about how they keep them -- they seem to have them listed for quite a while, so probably they found a way to keep them healthy.

Mike, i've no Problems with them. But I would point out how sensitive they are. Therefore my post here.

I saw on Facebook that Wetspot has the animals on the stock list ... and after they had already sold 30, came the question whether it would be very aggressive. I think a question about the animals there is no need...
