clown goby and food

[Reef Frog]

My understanding is that CGs are easy to breed in captivity. Hopefully the ones we see here in the USA are not caught with cyanide. I would think they would be one of the easier fish to catch in the wild.

Sorry you lost your fish. If it was taking food into its mouth, it was ready to eat. The food was probably just too big. If you try again I'd mince the food or try smaller food. Most small fish go crazy for prawn or fish roe (eggs). They're very nutritious. They're also neutrally buoyant which means they are easier for the fish to find. Feeding in QT is a great idea and helps the keeper get things right and fatten them up so they can competed successfully in the display, as well as help you from introducing a disease.

Also, they can take on a splotchy appearance when sleeping and when stressed or frightened. I wonder if you confused that with ich. If it was Ich the goby had, keep in mind that the display could be infected now. There are measures you can take to correct things, but there is a good chance that reef safe remedy you bought at the local fish store will not work.

Huh wow that sucks.. I figure that kill them maybe its a very small amount.

I didn't know they do that. I asked the LFS guy the other day about that to that maybe it was wild caught and he said he didn't think they get wild caught fish but who knows for sure.

Usually a good lfs that import their own fish hand pick their suppliers and know how the fish are caught, or farm raised or captive bred. The ones that care mind you!
Unless there is an intermediate ( third party) in the supply chain then it is sometimes harder to find out how the fish were caught. But there are the " better" wholesale suppliers who won't ship sick fish.
Most clown gobies are wild caught because while they're easy to match up and spawn readily in aquaria the fry are quite tricky to raise on account that they're so small.
If you look up Coral magazine's marine captive bred species list for 2013-2014-2015 , you'll see that it's been done ( g.okinawae) but it's a sporadic thing I don't think anyone has set up commercial breeding . However a few people now successfully breeding g. Citrinus.

Good information. Plus they are an inexpensive fish. I suppose that would suppress captive breeding efforts to supply the trade.

Thanks...lol [emoji4] .... I only know this because over the course of 3 years I tried to have 4 different species breed... 3 spawned like crazy but never got the fry past day 4 because back then almost no one supplied rotifer and copepod cultures.
A few months ago I decided to try again.... Pairing is in the works [emoji6]

I guess I try to do my best to stick with captive bred. lol

I read on a link there was a test developed to detect if cyanide had been used on a fish. Do they require that on import of fish or anything yet? or is that too expensive? etc..
