Well, the mystery deepens... they look different from the ones collected from Karnataka.
Don't have a clear explanation, but my 2 cents on this is that the channas are still not a popular aquarium fish and there are a fair no. of variants yet to be discovered. Some of the species like the gachua, striata, stewarti have been sometimes been categorized as a complex. This means that there are a fair no. of similar yet distinct (sub) species.
For example, a Channa sp 'True Blue' is considered by many to be part of the stewarti complex. Same is the case for sp 'Meghalaya Leopard' and sp 'Patterned'. In fact, it gets difficult to identify some of these when they are stressed and their typical coloration is not visible...
So you never know... u may have either a color variant or a new sub-species...
i second you Ajay... There should be a fair no. of similar yet distinct species.. And I hope there are much more to be discovered yet!! :D
"sp. turquoise" is a trade name applied to a gachua like fish from Assam. It has no taxonomic basis. The word "turquoise", just like the words "true blue", "meghalaya leopard", "violet moonbeam" etc., is designed to help sell fish.
Opinions are divided on whether "sp. turquoise" represents a separate species or just a form of gachua. Last I heard, the argument for a variant of gachua had the upper ground.
In the interests of clarity, it is better to restrict the "turquoise" to blueish fish from Assam. The fish from Karnataka would be best represented by Channa cf. gachua "Karnataka" (or name of water body it was collected from). If you want a fancy name, call it sp. aquamarine or something. Please don't add to the confusion by insisting on applying the same trade name to different fish.
Agree with you that these are "decorative" trade names which are are obviously used to market the fish (especially in the Export market) but we as hobbyists would definitely find this as our only platform to discuss the variations in the fish and we surely wouldn't be wanting to add confusion even if we want to Rahul, at least not intentionally ..
nice to meet you. I hope we can meet up some time and discuss and share our experiences with these beautiful fishes. I had a small C. marulia, from Srirangapatnam, but sadly that little guy jumped off a very small hole in the lid and became cat food. :-(
Looking forward to meet some Channa - enthusiasts.
Hi thanks for the welcome, have to admit though that I am a channa-less enthusiast these days, hence I am looking for breeders or people who want to give away some of their fishes, so I can get my hands on them again :-)
