I finally managed to get a reasonable photo of the smaller adult 'Annamia' specimen in the River Tank so that it can be compared with the larger, bolder one. The small one is just under 2" total length, whereas the bigger checkered one is approx 3.5" total length. The markings seem very different. Thought it might help with eliminating one possibility from the equation???..or not???....
Here they are:
Smaller 'Annamia' (which came from the same batch of fish as the larger one):
Larger 'checkered' Annamia:

Thanks Graeme.
I mean Annamia and Sewellia both have less than 5 anterior pectoral fin rays that is not branched [actually 1-2]. In Sewellia the pectoral fin would expand back to overlap the pelvic fin. From various pics I think Sewellia should have at least a few more pelvic fin rays than Annamia too.

How to Count?
Could anyone explain how to count the number fin rays and how this aids in identification?

Nah, we keep all equipment separate, mikev. The Clown Loach tank is very large so we use a wide bore hose to do water changes (we siphon the water straight out onto our patio). The River Tank is much smaller, hence the hose I use is a different (much much smaller) one. Don't use gravel vacs as we have sand substrates in both tanks. Any nets, buckets, algae scrapers etc etc are all kept and used separately.mikev wrote:Hmm, no good candidates on this list. I think that the babies are loaches.
Maybe it still worth checking for other contamination possibilities, like sharing a net, or gravel suc, or anything of this nature....

Use this Sewellia pic by Emma as an example the 1st pectoral fin ray is not branched, while all other pectoral fin rays are branched near the end tips. The number of visible branched pectoral fin rays is at least 14-15 if my eyes is not too bad. The pectoral fins seem to clearly overlapped the pelvic fins. Each pelvic fin seems to have one unbranched ray and at least 14-15 branched rays [probably more]. In other fishes eg. cyprinids [barbs, barbels, daces, rasboras, danios, tenches, etc.] the branched and unbranched fin rays of pectoral and pelvic are not counted separately.

Here's another installment in the loach fry development! Taken this afternoon 29/06/2006:
First off, a bit of a 'group shot'. Over the last couple of days I have noticed that they are starting to 'cling' more to the sponge and the glass. As you can see there is one haging upside down from the sponge on the left hand side of this pic:
I was pleased with this shot of the underside of one of the fry:
Another little gathering:
Look at that mouth!
