Rhinogobius wui

[OohFeeshy]

Hopefully I'm getting a hex tank soon (free). Not sure on size, I estimated 5g for nor because thats the smallest hex size and, well, if not, I could get one Anyway, I asked CFC what he thought I should have, and he said.... Rhinogobius wui. White cheeked goby (I think) or Dwarf Dragon Goby. Same thing. This os one of the fish I can actually get , so I thought Hey, Why Not. The web doesn't have much info though, and it obviuosly varies. So, how big do they get, what are they like, breeding (hoping to get a m/fm pair) etc. Anybody?

Or anyone suggest anything else? Bear in mind, the selection of fish I can get my hands on is similar to the number of attendees at Chess Club at school . For those of you behing the times, about one person goes .

They grow to around 2 inches and are great little fish with bags of character. They dont require a heater providing the room doesnt get much colder than about 10 celcius and as they are so low waste producing only a simple sponge filter is needed. Males can be easily identified from females by the bright red area on the throat, if more than one male is kept they flare at each other by inflating their throats (they look like little dinosaurs). A sand substrate and a flat rock or piece of slate it the only furniture needed for the tank, the gobies will excatvate tunnels beneath the rock where they will breed. Breeding is very simple with usually just a water change triggering a spawn, the female lays 8 to 12 large eggs on the underside of the rock and the male will guard them till they hatch.

Thanks, that makes them sound perfect I have a spare heater, but its a bit up the creek, and my room temperature keeps tanks plenty warm. I also have a spare sponge filter, although I'll probably go for the Elite Mini because its nice and quiet. I already have slate too Darn temptations

ooooo.... i have a heavily planted 10g that will (one day, someday) be empty of livebearer fry and contain a betta and 2-3 khuli loaches. would a Rhinogobius wui be a nice addition to the mix?

my substrate is Seachem Flourite.

These are really neat gobies. Besides freshwater they do well in brackish water as well (I've kept some at half strength seawater for a few weeks).

They're basically very tough. One thing they do not do well with is continually high temperatures. They need subtropical conditions similar to those of things like ruby barbs, white cloud mountain minnows, hillstream loaches, and Variatus platies. If kept in tropical tanks they are short lived. In my experience they seem not to put on weight (hyperactivity?) and become prone to dropsy (I've seen this 3 times). My guess is that oyxgen levels need to be high for start, and in warm tropical conditions this isn't always the case. But in a coolish tank with fast water, a few water-worn pebbles, and a school of mountain minnows, you'd have a great little set-up.

Mine have no interest in flake food, but accept all sorts of frozen and live foods.

By the way, these fish are correctly called Rhinogobius duospilus, so if you're searching for info under the "wui" name, you're likely to miss some of the newer stuff.

well, dang. there goes the marriage between oddball & betta when you say "subtropical", what temperature range does that encompass? (i'm not giving up just yet!) also, when you say "tough", does that mean "armoured" like bumblebee gobies or just "hardy"?

PS: neale, did you see this pic i put up of my SAP?

Thanks for that, I'll try out the other name I'd rather keep them in FW, my guess is the shop do that and I don't particularly want to engage in brackish yet. Room temperature should keep it nice and sub-tropical, the filter can pack plenty of oxygen in too. I'd rather go species tank, IMO 5g is too small for WCMM, and I'd like to keep as many fry as possible Foodwise, I can get cheap live bloodworm so that should be no problem either.

By subtropical, I mean around 15 to 18 C rather than 20 C upwards. So essentially room temperature in summer, and only minimal heating in winter assuming your house is centrally heated.

As far as "toughness" goes, I mean their overall hardiness. My guess is that they will be eaten or bullied by anything very much larger. But minnows, danios, and small barbs should be fine. They're really friendly fish, and spend all their time on view either fighting or looking for food. Great value fish, far different from the usual boring gobies that hide all the time and demand live food (i.e., bumblebees!).

Hadn't seen the South American puffer picture. Very nice. Oddly, mine has no interest in Hikari algae wafers or catfish pellets. He mostly eats bloodworms, lobster eggs, and live daphnia. I guess he's a little spoiled, since I need to feed these things for my halfbeaks and glassfish.

By the way, depending on the size of the photos you take, you should run them by the picture editors of magazines like TFH. I've sold several pictures. Your picture is at least as good as the ones I've sold them. Requirements vary with each magazine, but basically they need around 2000 by 1500 pixels, 300 dpi. That's equivalent to the "high res" setting on a standard digital camera.

Rhinogobius wui, I will hunt some down
Goby list:
Candy striped
Goo obo
Peacock
Mogurnda clivicola
Mogurnda mogurnda*
Desert goby*
Rhinogobius wui*

 

[pica_nuttalli]

heh, if you can find them and breed them Dwarfs, i'll buy some of the offspring--even if i have to redo all my tanks to keep them!

 

[OohFeeshy]

Pica, if mine breed then you can have some Free gobies for everyone

 

[Dwarfs]

I wonder how they'll make it across the atlantic

 

[CFC]

Same way as they made it across the Pacific i should think, by hijacking an airliner and demanding to be taken to a new country

*imagines a goby with a large sub machine gun to the pilots head screeching 'I've got my rights!'*
