Spawning Dicrossus maculatus

I first remember this seldom-seen Checkerboard cichlid from when I was a teenager in
the fifties. I had gone to a Western New York fish show with an older member and his son.
From there we visited the home of another young member in the area. In a tank in his room
he had a beautiful pair of Spade-tail Checkerboards. Ever since that day I have been
keeping my eyes open hoping to someday find a pair. After over forty years I finally had
success. This spring of 2002 Paul McFarlane and I got a price list from an importer in
Montreal. On the list was Dicrossus maculatus. An order was soon placed and few
weeks later along with a number of other varieties they arrived safe and in excellent
health.
The first thing that I did was check the water in which they came. The water was fairly
soft and slightly acid. I duplicated it the best I could filling a ten gallon aquarium. In
the tank I put a box filter, a clay flower pot with a hole in the side, a clump of Java
moss and a small potted radican sword. I left the bottom bare so that it was easy to
clean. It did not take me long to discover that these fish are rather timid and would only
eat live food. Since I had a good supply of daphnia in a tub in the back yard this was no
problem. Weeks went by and the male that is about three inches long started to get a
little bit aggressive with the female who is an inch smaller. Most of the time she stayed
in the clump of Java moss or behind the filter. If she ventured too far out she was
quickly chased back to her safe hiding place. He did however allow her to come out to eat.
This went on for a couple of months. I was starting to get a little frustrated with the
fact that the female was plump but no spawning had taken place. The water had a pH of 6.6
and my conductivity metre read 180 microsiemens. My next move was to make the water even
softer. I started doing my water changes with straight RO water. Soon after a couple of
water changes things happened. It was now late June and one evening I was surprised and
delighted to see the female with her red ventral fins hovering over a clutch of eggs. Two
days later however, to my disappointment the eggs were gone. Within two weeks they spawned
again. Just as before, she had spawned on the radican leaf. There I was torn between
taking the eggs and hatching them artificially or taking another chance with mom. After
all most first spawnings of eggs are no good anyway. I noticed that things had changed.
The female became very aggressive and gave the male a good whack whenever he came too
close. On the third day the eggs hatched and there was about seventy-five little wrigglers
on the leaf, (I hear that they can lay up to a hundred and fifty). The next day they were
gone. What a disappointment. Not only that but the female had gone into hiding. The
following evening however I could hardly believe my eyes the fry were back on the leaf
with mom standing guard. Soon the fry were free swimming and followed their mother in a
tight little school wherever she went. The male found that it was best if he spent most of
his time in the Java moss leaving the female and fry most of the tank in which to roam.
Each night just before lights out at 11pm she would bed them down for the night on the
tank bottom. When they were about five weeks old and a little more than a quarter of an
inch long. I decided that seeing that the male was starting to move around too much and
the fry were ranging further from the female for her to feel comfortable. And that it was
time to move both parents to another tank. The fry I felt were too small and sensitive to
move. All this time the parents and fry had been living on newly hatched baby brine shrimp
with a few white worms for the adults occasionally.
The maculatus fry are not the easiest of fish to raise. They are very
sensitive to water changes and conditions and I find them to be slow growers. Now at a
inch long and three months old they are starting to spar amongst themselves. In spite of a
few losses I still have about fifty fry and the parents have finally quit sulking and are
showing signs that they might spawn again soon.
If you are fortunate enough to come across these fish don't buy them unless you are an
experienced keeper and breeder. It is a great feeling of accomplishment to have any
success at all with this little cichlid from Brazil. But it only takes one good pair and
lots of good luck.
