Siamese Flying Fox/siamese Algae Earters The Real Ones?

[mph130]

I have recently purchases a saw (Siamese algae eater) it has the stripe all the way through to end of tail however am unsure if is definately the real sea or a flying fox as quite new to fish. Can any one help me out - I'm pretty confident it is a true sae but just want to be certain as it might seem to be a bit aggressive towards my corydoras and it seems to be just hovering at bottom back part of the tank a lot - I have pics of it so can let me know if definately is the real sae. Cheers for help

a true SAE will have the stripe as you say but the edges will be jagged and not perfectly straight like a flying fox or false SAE. it will continue to the end of the tail fin and normally goes into a point. it should have a silvery belly and a golden back/top. they will also only have 1 pair of barbels, the others have 2 pairs i think......
they cant stay affloat like other fish due to their swim bladder so they need to be constanly swimming to stay in the water column otherwise they will sink, the same applies to loaches. this behaviour sometimes makes them look like they are darting or not right but you will soon get use to it

There has been a lot of work done on SAE and the fish considered as the true SAE C. siamemnsis actually is considered by many to not actually exist, Crossocheilus as a family are usually very palcid and wont bother any other fish.

If memory serves me right I am certain the fish previously considered to be C. siamensis is actually classified now as Crossocheilus langei, others that are very similar include C. atrilimes and C. nigriloba

i have to say that my SAE only ever bothered other SAE's and when a single specimin didnt bother anything

The easiest was to tell between a SAE and a Flying fox is to check above the jagged black stripe, if its a Flying Fox, it has a thin gold stripe above black stripe, if it doesn't have the black line, then its a SAE.
Majority of SAE are very peaceful. My pair of SAEs are little angels but elisew had a badly behaved one , can't remember what it done, but I think it ate chunks out of other fishes. Anyway, she ended up returning it
