RE: Newbie fry questions
Hi John,
Not to worry. Whether the fry grow quickly or not as long as they look
healthy they will usually become healthy full size adults. More water
changes will help. As will increased feedings and larger water volume to
fish ratios. Also some of the growth rates which are published are maximum
rates published by some very experienced breeders who are doing everything
right. Imagine how nice it would be to have time to feed live foods 4 times
per day, do weekly water changes, or to have a rack of large empty tanks
Waiting for dozens of SJO fry. Some breeder with limited space cull their
fish so that the space to fish ratio is better.
I had a group of Fry in a 2.5 gal tank. After about 6 months they were all
under 1/2 inch long. But the males were in good color. When a larger tank
became available I moved them into it they expanded like dry sponges hitting
water. I was not trying to retard their growth. But things are what they
are.
Much to do has been made about fast vs. slow growth. My fish get as much
space and food as I can provide. Sometimes both space and live food are
limited. If you are in a race for some reason buy larger tanks, change more
water and raise more food. Otherwise just enjoy your fish.
So my advise to you is just give them as good a home as you can. As long as
they are healthy you are doing OK. By the way 27 adult SJO would be a tight
fit in a 20 gal tank. This may be a case where you may be better off not
getting what you wish for too soon or at least until you get a lot more
space set up for these fish.
Best regards,

Subject: Newbie fry questions
Hello all,
I have a few questions regarding fry. First question is about growth
rate. How fast should my fry be growing? I am currently working with SJO,
AMI, and WAL. It seems that they are growing so slowly I must be doing
something wrong. I have a batch of AMI that hatched out on 7/17 they are
over 4 months old. I am new to killies but I was under the impression that
killie grew very fast and would be full sized adults in about three months.
But my 4 month old AMI are between 1/4 and 1/2 inch. These are my oldest
fry. I have many more batches of all three species growing out. Is this a
normal growth rate for AMI and Fp . in general? or am I doing it wrong.....
I have about 27 of them in 20 gal tank with lots of Java moss a sponge
filter, Strong lighting on a timer (14hrs/day) I feed mostly frozen bbs and
mix in Moina and grindal worms. Most days they get fed once and some days
twice. I kept the tank heated (temps in the upper 70s)
I assume that the factors governing growth rate of fry are:
Temp
Length of Day
Frequency of water changes (2x month now)
Density of fish to water volume
Aggression
Amount and quality of food given
Genetics
Am I missing anything?
On a side note I was also wondering what kinds of Grow out Densities
people use ie.. 1 fry in a 10 gallon tank or 100 fry in a 1 gallon shoe
box.... is there any guide lines. For instance 2 fry per gallon of grow out
container.
BTW... I realize growth rates are all going to be different based on species
and making generalizations is dangerous. This is why I listed the species I
am working with. Any advice will be greatly appreicieated.
Thank you,
John
