Curious breeding behaviour in wild fixed archocentrus sajica - pets
I would like to write a few words about my experiences breeding wild fixed Archocentrus sajica and a amazement that these fish gave me - a amaze that shows the fascinating and diverse behaviour of these animals.
I got a pair of wild-caught sajicas from a associate who had cool them on a trip. Since I had kept this species already (in fact it was the third cichlid I ever bred), I didn't be expecting any surprises. Well, I was wrong.
For want of change for the better accommodations I put the 6 cm/ 2½ inches long cichlids into a 540 litre/145 gallon aquarium that was previously overly crowded. In the aquarium previously swam four 20 cm/8 inch Texas cichlids, a pair of N. festae (25 and 20 cm/ 10 and 8 inches), a pair of N. managuense (about the same size as the N. festae) and four Natal cichlids, Mossanbicus mossanbicus, (20 cm/ 8 inches). The tank was also inhabited by two convict cichlids (about 4 cm/ 1½ inches) that had first been put there as feeders, and after all loads of Ancistrus that just wouldn't stop breeding. All of the species were breeding evenly in the aquarium. As I said, the aquarium was before now very crowded. I knew I was captivating a attempt putting the small sajicas in with these predators, but I didn't have any choice.
To my great relief the sajicas found themselves loving their band and were left alone by their superior grasping cousins. The aquarium was decked with two very large roots that reached all the way to the appear of the aquarium and which produced three biological territories for the fish in the aquarium. There were small gaps under the roots that the ancistrus utilised for breeding. The bigger cichlids couldn't get into these spaces. These large roots made the water in the tank very dark and made it look like a black-water river aquarium. But the water was harder and the pH level advanced than what you might assume to find in a black-water river.
When the sajicas had been in this aquarium for a week, on a diet consisting chiefly of Hikari pellets and shrimps, they spawned for the first time. Any person that has kept A. sajica wouldn't be bowled over about this, the astonish would be if they didn't breed at some point in the first month. In spite of this the astonish was how they bred. My come across is that sajicas are committed parents that watch desperately over eggs and fry. But under these environment this pair chose a assorted approach. The female laid her eggs on a root intermediate to the surface. Her eggs had a much darker tone then A. sajica eggs as a rule have, and matched the colour of the root more or less perfectly. This was a touch the parents seemed to be aware of, since they didn't care about shielding their young. They both swam all over the aquarium just as already the egg laying, and it wasn't atypical that the two fishes farthest away from the eggs in the total aquarium were the sajicas. Intermittently they did chase away some ancistrus. You would think that this astonishing parental behaviour would mean the end of the eggs in an aquarium where more than a few fishes could eat all eggs in one gulp. But this was not the case and about all the eggs survived and hatched, at which time the parents moved them (spat them) under a root where not even they could get in. They then constant performing as if nil had happened. When the fry were free-swimming the parents took their young out for expeditions about 1-2 hours each day. The rest of the time they left them under the root, where they evidently found food as they grew nicely.
The parents constant to take them on these a small amount expeditions for about a month, after which the fry had grown to approximately 1. 5 cm / ¾ inch. The impressive thing is that more or less all of the fry had survived to this age. After the parents had clogged caring for their fry, the young cursorily became bolder and on track swimming around, which led to all but two of the fry being eaten one week later. (There had been 50-60 fry beforehand that). These two conversely did deal with to grow up in this aquarium.
The wild fixed A. sajica connect spawned many times in this aquarium, once every 2-3 months, and they at all times had great achievement using this method. At one point I moved them to a further aquarium about half as big as the other and with clear water. They common this tank with a come to of other cichlids, as a rule fry from the better aquarium. In this aquarium they spawned in the way one is used to considering A. sajica spawn, i. e. continuance guard over their eggs and fry. A diminutive later the connect was moved back to the 540 L /145 gallon aquarium and they then on track to "hide" their eggs and fry again.
Out of curiosity I also tried maintenance them in an aquarium with clear water and a large pair of N. managuense as company, and the sajica connect spawned durable guard over their eggs and fry. It seemed like they austerely chose a new approach in darker waters. I have kept other pairs of breeding A. sajica in the 540 litre/ 145 gallon aquarium since then, but none of them have shown this behaviour. I'm on tenterhooks that others get to encounter this distinctive behaviour that just goes to show that cichlids never stop being surprising.
