54 L tank : 25% waterchange, KH 2°, pH 6.8, 30° C.
The BIO CO2 bottle
started CO2 production tonight and pH moved slightly below 7.0
After ordering O.S.I. micro food yesterday I ordered 1 L of
Javamoss and will create a Javamoss garden in the breeding tank.
If some fry will survive in the tank the moss shall give them
shelter during the first critical days.
I have a new plan how to arrange strobe lights to improve quality
of the Rainbowfish photos. (my plan fits, look at the 2nd
photo at the right side). The best time is during the
morning because then the males show their most intensive colour.
The male that looked quite aggressive the last 2 days will stay in
the breeding tank because he changed his behaviour. Clever guy !
I've read it several times but didin't believe it. It's better to
keep I. werneri allone in a tank. The fish in the breeding tank
look much better and eat better than the werneri in my show tank
where they are in competition regarding food with 5 M. Praecox and
3 P. signifer. That's not really a lot of fish in a 240 L tank but
I. werneri get definitely not as much to eat as they need to look
really good and feel good. Maybe I modify my plan a little bit and
put some adults into the outdoor tub....

I've added some Myriophyllum. Water temperature was al ittle bit
higher this morning. The heater is working but there must be
something wrong with the integrated thermostat.

Nothing special happened
today, all fish lare looking fine. I will change
water every 2nd day in the future. This morning I took the shots
of my mating males that I've been wanting to take since a few days.
You can find them below the couple shots on this page. They show
indeed very deepcolour while mating. Hopefully the moss will
arrive tomorrow so that I can redesign the tank a little bit. It's
quite hot at the morning, I#ve to adjust the heater tomorrow to
have maximum 30° C.

The situation between the male I. werneri is definitely
more relaxed now. Obviously it took some time to find their place
in the new home. I haven't seen any eggs yet but I must say that
I haven't searched the Javamoss to avoid additional stress. If
they're destined for laying eggs....they will lay eggs ;-) The
moss new hasn't arrived yet.
P.S.: each day has 24 hours and.....now I found eggs in the
moss in the evening. I removed wood with moss because I
wanted to add soe dark red gravel and put some more plants in that
I had cut from my heayily (too heavily) planted show tank. The
plants are growing so well that I could create a heavily planted
80 cm tank all two weeks without buying a single plant.
So I touched the moss and I had 4 eggs on my finger. I didn't go
on searching and have put all the moss into a 40 cm (25L) tank.
O.S.I. micro food will arrive tomorrow and a lot of new moss
I will keep the I. werneri also in the 54 L tank in the future.
Therefore it will be heavily planted in the future, too. O.k. The
challenge raising fry is starting exactly now.....
- outdoor tub - 25% waterchange, fertilizer
I'll put two couples of Iriatherina werneri out of the show tank
into the outdoor tub. I'm sure they're not feeling best among the
Paecox and for breeding I think putting them into the breeding
tank would be too much of a good thing for 54 L. I'm not sure yet
if I will use mobs or just wait if some fry will raise in the tub.

There's no moss in the tank any more so they started
spawning between the Rotala this morning. I'm very confident that
I will raise some fry because the adults feel very well and are
obviously spawning each day now. Even the removement of the moss
and putting in some gravel didn't actually irritate them.

30% waterchange, KH 2° C., pH 7.0, 29° C.
HURRAY !!! Approx.
20 little fish in the tank which are 4-5 mm small. I will
update this report later and probably take some photos if possible
;-) I'm busy right now ;-))))

just in time and my fry started eating well. Everything
looks great so far. It's impossible to give them only as
as they really need. A litlle spoon came with the micro
food. Half of
it would reach probably for one month:-) I'll try to find
the right dose by using a toothpick. This is what I do when
feeding cyclop eeze to the adults.
- outdoor tub
Something quite stupid
happened. I've put some swimming plants into the outdoor tub a few
days ago. In that plants must have been some eggs of Tanichtys
albonubes. This means I've some fry in the tub at the moment. When
I saw the werneri eggs yesterday I've put the moss into the tub
first. After two hours I changed my mind and put it into the 25 L
tank. My current opinion is that I've some fry from two different
specimen in the tub ;-))) So removing fry makes no sense. I just
will wait what they will look like when they're about 7 or 8 mm
big when the T. albonubes start shimmering and getting a glowing

The moss arrived today and I'll tape it upon some lava
stones. Next week some more moss will arrive, so it should be
possible to raise some Triatherina werneri fry in this tank
together with the adults. I'll give this method a try, too,
because hopefully enough fry will raise in the 25 L tank and I
don't need some hundreds of I. wernery (....well, actually ;-))

I counted about 50 little fish today. The're still very
active and eat well. Seems that things are doing fine. I tried to
take some more photos but that can drive you insane. Depth of
field of my lens is about 2 or 3 mm and if fry doesn't swim
exactly parallel to the lens exactly in the depth of field area,
it's a 2 hours job to get one photo of reasonable quality.
Until today the fry only swam directly below water surface. Now
they started swimming also 10 cm below and are becoming more
My 10 days
To get some fry was easier than I
thought. I was told that I would need luck and perseverance which I
can confirm. Although I write that it was easy (this time) I know
that I surely had luck because I felt some eggs in the moss with my
fingers and then put them into another tank. If I didn't touch the
moss I never would have recognized some eggs. But the hardest step
is still in front of me...bringing them through the first two weeks.
And I had excellent support at Gunther's forum
rainbowfish.info !! Thanks to everybody for some excellent
Adrian Tappin who supported me with excellent tips late at night
(for him down under it was morning ;-) If you're looking for any
kind of information about rainbowfish, visiting Adrian's website is
a MUST !!
What have I done to get some fry
- Giving my breeders time in the
240 L heavily planted show tank to improve their bad condition
from the dealer's tank (about 6 weeks)
- A tank for the I. werneri
themselves, at least 54 L as a breeding tank
- A mix male / female of 1:2
- Feeding newly hatched brine
shrimp and Cyclop eeze 4 times a day
- 25% waterchange daily
- KH 2°, pH 6.5 - 7.0, temperature
- Javamoss as a spawning substrat
I don't know if I had the same
success if I would have done a waterchange only once a week or if
I wouldn't have increased temperatur, etc.....For me that doesn't
matter. It worked the way I did it.
