heloo mates,
i have a fish.lfs guy told me that its name is major sergeant.its a pretty fast fish and it eats like a PIG!! well,when i searched over internet about this fish i found out that it is a saltwater fish from
-->family: Pomacentridae.
-->scientific name: Abudefduf saxatilis
lfs told me that this fish has been converted from marine to freshwater!! well,is that possible?i will try uploading the pics by photobucket..

sorry for my SUPER BAD QUALITY.the base color of this fish is green.has black stripes on it..and it has sparkling green colored spots like jewel on it.

it may grow upto 15 cm!!

but my question is can a fish be converted from marine to freshwater??

also it may be Abudefduf taurus or night sergeant..somebody plz tell me what this fish is exactly that is swimming in my tank!!

Some fish are able to survive and live in both freshwater and saltwater, mullet, salmon eels etc, but I've never heard of converting a saltwater fish to live in freshwater. I would advice you need to buy fish that you know and live in freshwater. If you put a saltwater fish in freshwater, or vice versa, it will die eventually, & probably quite horribly.

My knowledge of marine fish is almost entirely limited to UK fish , but the photographs you have posted do look like a sergeant major fish, which is indeed marine

I looked them up for you and the Sergeant Major fish is actually a damselfish...Abudefduf saxatilis...and yes it is saltwater...I don't know how it would be able to be converted to freshwater as in the wild they live in tropical climates near reefs and are plankton feeders.

I would suggest getting it to someone with a saltwater tank or setting up a saltwater tank for it...like OFL said in the previous post it would be a painful death if left in freshwater.

i have green spotted puffers i acclimated from 100% freshwater to full strength seawater of 1.025sg, and back to 100% freshwater with no problems over a period of 6 weeks for each change. it can be done!

well the lfs guy told me that he was having this fish over an year or so....n guess what ??

i am with a bad news...most probably sergeant major pecked my baby oscar's fin right now..n now iam angry like anythin..

That's terrible, about the pecking. I am 100% positive you can't "convert" a freshwater fish into a Marine fish. It's just not possible. They have an entirely different blood chemistry.

Is the fish acting weird?
