Rhinogobius sp. Info

[Thyroyalgeek]

Okay, i have a ten gallon tank which i'm narrowing down the stocking in. I preferably would like an oddball ( preferably, yeah right, oddballs are a must.) Any who, I have it down to three possibly four things, of which one is rhinogobius, this will be in a ten gal. With clean frequently changed water any info appreciated

I'm still listening

 

[Thyroyalgeek]

Anybody?

I don't really know much about rhinogobius species I'm afraid, but I'm also looking into getting a few! Some sites suggest brackish water for some species, others say all of them a freshwater. The best source of information I could find on them was Rachel O'Leary on YouTube. She keeps hers in a massive hill stream tank and feeds them live food I believe, I think I remember her saying that they don't take to pellet, and it's difficult to get them onto frozen or freeze dried. I'd suspect a 10 gal would be adequate for 3 or so, considering their size and activity levels.

Thanks. So far I've only heard that they were freshwater. Didn't know they were brackish too.

I've kept both Rhingobius leavelli and giurinus before and lots of luck with them taking prepared food. My giurinus in particular took pretty easily to flake and pellet food but also relished bloodworms. These were in a cooler temp (72°F) tank with some plants and a sand/fine gravel mixed substrate. I had a mixed sex group and the main thing that stood out to was the aggression of both males and females, I had a male kill another male and females would take turns beating on some bitterlings I had in the tank. Never killed other tankmates that weren't Rhinogobius, but I'd be wary in a tank as small as a 10 and depending on how much my experience holds true for other species in the genus. Wonderful personality though, make sure to positively ID whatever species you get, as mentioned above some are from faster flowing waters while I've netted some out off of concrete slabs in Japan in a few ponds if I IDed them correctly.

How many could I keep in a 15 gallon, 4?

I started with 6 giurinus in a 29 and ended up with 4, so depending on species I'd be a little wary of that many in a 10 but that's just been my experience thus far.

I accidentally typed 10 gal, its actually a 15. So would three be okay? Problem is finding a place to get them.

Three would probably be okay provided it was a male and two females. Going back and doing some rereading and Seriouslyfish actually recommends keeping this species in mated pairs if possible, though I didn't know this when I bought mine. The ones I got were ordered as I believe "Barcheek gobies" from the LFS I work at and I subsequently haven't seen them since unfortunately. I haven't checked Aquabid for gobies in some time, though I would imagine a more specialty place like The Wetspot sells them on there from time to time. This is one of my male Giurinus I believe, stunning if mean fish but it sounds like they're maybe less commonly seen than other Rhinogobius sp.
