ID this fish please

What is this fish?

 

[OrangeCones]

Monodactylus argenteus would be my guess.

 

[Alex2290]

Thanks I think that is what it is! Seems rather difficult to keep. The place we ordered fish from threw one of these in a box for us. I'm guessing it was an accident because we didn't order it.

They are quite difficult to keep, they get quite large and require increasing salinity in the water as they grow, as adults really needing a marine set-up. I'd send it back unless you can cater for it.

Oh hey, here's a school of them full sized!

I need another fish ID'd. I have seen it before but I just can't remember the name...

I got three of these fish when someone gave me a free 10gallon tank.

I don't want to put them in any tanks I have now as 1) they may eat my shrimp and 2) they came from a tank with a LOT of snails. Will they survive overnight in a cup with no current until I can bring them to someone in the morning who will take them?

The 10 gallon she gave me is brand new and not the one they came from. She didn't want to give me the other tank because she didn't want to give me snails, or something.

Long-finned zebra danio. Won't eat your shrimp so I'd put them in with them until the morning, they will not do well overnight in that cup. I doubt you'll get any snails in with them.. just net the fish and you should be fine.

That's what I thought the fish was, but I wasn't very sure...

I'm not so concerned about getting snails as I am about my RCS being eaten. These danios are at least 2 inches long, and everything I read on the internet says that they will eat shrimp. Most of the shrimp I have in the tank they would go in are 1/4 - 3/4 inch. I don't want to keep them in the container, but I don't know what else to do. I have a few kordon breather bags from a few months ago. Would those work?

 

[misterking]

If theres some way you can get them in the tank water without mixing them with your shrimp (wasn't expecting them to be that small!) I'd do it. Otherwise I guess the breathing bags will have to do.

 

[IThinkTherefore]

If you can cut small holes or slits in the cup and clip it to the side of the aquarium, the waterflow would be very helpful

 

[aakaakaak]

Sure, danios eat shrimp........brine shrimp....

It's also very rare to see a fish carry snail eggs. It's probably not impossible, but unlikely.

 

[Alex2290]

They survived the night in the cup. I would have put them in the breather bags, but I misplaced them somewhere. They went to good homes today. 2 went to a 30gal and the pregnant one to a 55gallon.

Now, what the heck am I going to do with this aquarium? I need a hood, which is like $40 alone... and a stand... Geez... After I buy the hood, stand and lights I would have spent almost as much money on it as a 55gallon with hood and stand costs on craigslist. >.<

No, those danios could definitely eat your shrimp. I have a longfin leopard that ate half a dozen cherry shrimp I put into my tank. Obviously he couldn't eat them whole, so he'd carry them around in his mouth until a piece would break off that he could swallow.
