Angels at Christmas
I purchased a Koi Angel from Petland that I just had to have
when I saw it, my wife then said to me that I must get another
one to keep it company, so a month later I saw another one I
liked at Aquatic Finatics so purchased this one. They are both
kept in a 4ft tank, along with Rainbows, Syndondontis, Corydoras
and Congo Tetras, they all get on fine with no problems.
Early November they spawned, but the eggs were eaten the first
night.
Then a week before Christmas, they started to clean the leaves
of an amazon sword plant, at one end of the tank and this became
very intense over the remaining days, then they both made sure
no other fish were near, in fact they chased all the fish to
the other end of the tank, even the syndontis. I checked the
water and the temperature was 78-80F and the Ph was 7.0.
Then on Christmas Day, I went to look at my fish in the afternoon,
and was amazed to see the angels spawning on the leaf, it was
really interesting to watch the female gently go over the leaf
and lay eggs, with the male following to fertilise them, I had
seen them after they had started, so was only able to observe
them for the last twenty minutes. I then kept looking in on
them, to see them chasing the other fish away, and gently fanning
the eggs, both fish did both of these chores in turn. However
the other fish were trying very hard to get to the eggs, so
the angels work in keeping them away became harder and harder.
I had to think what to do, as I did not want to lose them, and
also I had no spare tank.
I then came up with my plan, as it was Christmas we had a jar
of Quality Street, so I emptied the sweets out, I then filled
this with water from the Angels tank, and transferred the leaf
full of eggs to the jar. The jar was then stood in another tank,
to keep a constant temperature, and I put a gentle airstone
in so as to keep movement over the eggs like the parents would
do. I hoped they were fertile and that I would be able to hatch
them, to this end I kept a close watch on them, only to see
some eggs fungus over, the next day. Using a magnifying glass
I kept looking closely and was sure I could see the young developing.
On the Wednesday I was delighted when I came home from work
and went to check on them, to find that there were quite a lot
of babies had hatched.
This then gave me another problem as I still had no spare tank,
and I knew the jar would soon be far too small, so it was a
trip to my local aquarist shop to buy another tank, this was
to be a 30" tank, and this was set up straight away. By
the Sunday 1st January the fry were free swimming so I transferred
them to the new tank, and kept checking them throughout the
day. I started feeding them liquifry, mind this was the one
for livebearers as I was unable to get the egglayers variety
anywhere in Scarborough, anyway I knew the fish could not read
so it should be Ok.
On Monday 2nd January, the fry were very active and most of
them were swimming around in two shoals, one much larger than
the other, the remainder remained in a couple of groups on the
bottom of the aquarium. The fry swimming around were quite fast,
and moved around the aquarium with ease. I estimated there were
a few hundred fry.
The following day I noticed they were now in two shoals, swimming
close together, an interesting point was that each shoal occupied
one end of the tank, with no fry in the middle, in the evening
when the lights were turned down, the fry went to the bottom
into two balls, still at their own end of the tank. This behaviour
continued for a week, when the behaviour changed in that a number
broke up from the shoals, and the fry began to swim all over
the tank. Was the behaviour a way of protection I do not know,
however it was at this point that a number of the fry died.
A week later a large number of fry had died, and I estimated
to have around 100 left. The remaining fry were now starting
to get deeper bodies, and were very active, some of the fry
were bigger than the rest, but I was unable to sort them into
sizes as I had no other tanks available, so had to leave them
all together. By now some were a lot lighter in colour than
the rest, and some had black markings on them, so I was expecting
to get some different colours when they became adults.
I was feeding the fry three times a day on a mixture of dry
foods, crushed very fine, and as they got bigger increased the
size of the food. They soon got used to feeding time, and would
eat it with relish.
It was when the fry were four weeks old that their size just
seemed to rocket, and took on the proper angel shape. It was
at this point that a couple of the fry seemed to become the
bosses, and were the first to the food, and chased the others
away. There were a number of fry that never grew so these were
culled out, this would leave the stronger and healthier fry
more room to grow. I also selected 6 that I wished to keep,
and grow on to hopefully provide more breeding stock. By this
time I had moved some of fish about and had a spare tank, so
the six fish I had chosen were transferred to this tank.
The parents have since spawned again, once again I was able
to observe them spawning, and again they chose an amazon sword
leaf. However not having any spare tanks, could not attempt
to rear them artificially, and the eggs were eaten, I do not
know if the angels ate them or other fish were guilty, as once
again they had spawned in the community tank.
I am very pleased with the results as I never set out to breed
these fish, and only purchased two angels from two different
shops, both for a community tank. For them to actually be a
male and female and then pair up was a surprise. I plan at some
point in the future to attempt to breed from the parents again,
but in a tank on their own, and hopefully for them to hatch
and rear the babies.
