![]() Somewhat fussy, this fish should be acclimatized in slightly soft water, pH around 6.0 - 6.5. Least Concern, range map and more is available on the IUCN species page. Horizontal black / white alternating stripes on tail fin, the only other member of the genus has a clear caudal fin and is generally smaller.įemales are more heavily bodied than males.Īmazon (click on these areas to find other species found there) Log in to view data on a map. ![]() Shane's World Reproduction Notes on a spawning of Dianema urostriataĨ4mm or 3.3" SL. South American catfishes (Everything else).Once acclimatised, it usually proves very hardy and can be exceptionally long-lived for a fish of this size, having the potential to survive for over 10 years. This is at least in part because all specimens sold for the trade are wild caught. Newly imported fish tend to be a little delicate and are susceptible to disease. So named because of the row of spots running along the lateral line, the porthole cat is a good community species. The wet season occurs roughly between September and April, depending on geography, so it may be that some species will spawn only during these months. In the unlikely event of the fish still being unwilling to spawn, bear in mind that aspects such as barometric pressure and time of year can also affect breeding activity in many South American species. Replace the filter if you removed it, and if the hardness of the water was increased, use very soft (preferably RO) water for topping up. An increase in both organic compounds and dissolved salts is associated with the dry season, simply because there is less water around to dissolve them.Īfter a few weeks, increase the water level using cooler water and begin to feed the fish heavily. If you wanted to really push the boat out, you could also remove the filter (keep it running on another tank so it remains mature) and increase the hardness of the water slightly. The fish spawn at the onset of the wet season, so first lower the water level in the tank, increase the temperature by a few degrees and starve the fish for a few weeks to simulate the dry season. If you’re having trouble inducing a spawn, you could attempt a full-on simulation of the dry and wet seasons that occur in its natural waters. The fry should be big enough to take Artemia nauplii and/or microworm once their yolk sacs have been absorbed. ![]() Once eggs are noticed, the adults should be removed, as they may eat them. Apparently, copious amounts of live food are important to bring the fish into condition, as are large, cool water changes. Ideally, the object should also be secured in one place. ![]() With the closely related Hoplosternum genus, the most success has been had using a yellow-coloured object, so this may be worth considering. Add a piece of poystyrene or plastic lid of some kind to float at the surface and provide a potential nest-building site. If you want to try breeding these, it’s probably best to begin with a small group of 4-6 fish. urostriatum is reportedly a bubblenesting species, although some conflicting information exists suggesting that the eggs are laid in pits excavated from the substrate. Very scant information exists regarding the spawning of this fish in captivity. Mature females are likely to be rounder in the body than males. The leading few rays of the pectoral fins are thickened slightly in males. Oddly for a catfish, you will often see it swimming in a shoal in midwater when maintained in this way. Although it can be kept as a single specimen if you wish, you will find it far more outgoing and active if you buy a small group of 3-6 fish. It is totally unaggressive towards conspecifics. It is less suitable for a community of much larger or aggressive species, due to its shy, retiring nature. Ideal tankmates include other Amazonian species such as tetras, peaceful cichlids, Corydoras and smaller Loricariids. It will not harm even the smallest of tankmates, although tiny fry may be hoovered up. Behaviour and Compatibility Top ↑Ī very peaceful fish that is suitable for many communities.
