If this is the case, are there any suggestions as to what kind of shrimps may be beneficial for paros to live with? In the “Why are the Licorice Gouramis the way they are” by Martin Hallman, which is availible on the P-P website we can see such a sentence:
Licorice Gouramis are never found en masse in their native
waters, but they may occur in large numbers together with
shrimps in suitable places, such as beneath overhanging
turf or among the masses of small roots in holes in the
bank beneath trees.
So the date of the recording probably isn’t the first time such a behaviour was observed. Nevertheless, I believe that these shrimps should be mentioned in some way by teams reaserching the Licorice gouramis, and one who is able and willing should look it up.
So the question is, are these shrimps mentioned somewhere and is it possible to introduce them into aquaristic trade?
