[Peter Finke]

Film canisters (a pity: they are no longer easy to get!) are very suitable caves for many small fish, especially Parosphromenus. They normally swim; that does not matter at all. The fish look for caves, they find the canister and like it.
Nico’s pictures show P. parvulus “Tangkiling”. That is a location in the Palangkaraya-area. The original fish were caught by Olivier Perrin (Paris), as specialist of this species. Tangkiling-parvulus are quite nice because the males have rather broad whitish borders at the dorsal and anal fin. My parvulus are from Babugus, and the borders are less conspicuous. In any case parvulus is a remarkable species with it’s wild displaying dance and that head-up-posture. Most Parosphromenus display head-down.
Collect such film canisters if you can still get hold of them. The Paros love them, even the bigger species (not the biggest: qunidecim and real deissneri).
