tank : 25% waterchange, KH 3°, GH 7°, pH 6.0, 28° C.
GH increased, maybe
that's a result of putting the stones into the tank. I'll watch
this. Today I've put the last couple of Iriatherina wernerin from
my show tank into the 54 L tank. Now here live 4 males and 7
- 25 L tank :
30% waterchange, KH 3°, GH 4°, pH 6.3 morning, 7.5 evening, 28° C.
Yesterday I found some
fry in my 240 L show tank. I was successful in catching 13 of them
which I put to the Iriatherina werneri fry. I've no idea if they
are werneri, too or Pseudomugil signifer. We'll see....
Counting all fry is impossible but I gues there are at least
80 tiny fish now. Regarding different hatching times,
different sizes are already visible. So they're not only alive but
growing well ;-) Still fingers crossed !
tub : KH 3°, pH 7.5, 28° C.
As I wrote earlier some eggs of Tanichtys albonubes got into the
tub. I think with some swimming plants from another tub where I
keep the T. albonubes . Well...they're growing pretty fast without
extra feeding. I moved them to another tub today.
I'll give it a try to raise 25 of my I. werneri fry in the tub. It
looks like there's a lot of plancton inside. There are a least 50
little werneri left in the 25 L tank. I'm extremely curious how
they will develop compared with the fry in the 25 L tank.

tank : KH 3°, pH 7.0, 28° C.
I will now stop reporting
about the 54 L tank because this breeding project has finished for
this tank now. The Iriatherina werneri will stay in this tank
until a new 80 cm tank is set up. I made the decision to buy two
80 X 40 X 40 cm tanks tomorrow. They will be heavily planted tanks
and I will take a lot of time to design the two tanks and find the
- 25 L tank :
waterchange 30%, 3° KH, pH 7.5, 28° C.
I'ts impossible to count
all the little fish inside the tank but meanwhile I'd bat that
there are more than 100 !! Nothing new to report about this tank.
All are eating, growing and I can't see any dead fish on the
bottom of the tank. It's working prefectly so far. The little fish
are just three days old and I thought they have been living here
at least for one week ;-) I'm not sure how many days werneri eggs
need until fry hatch but it's possible that the number of little
fish will still increase the next days.
- outdoor tub :
changed totally over night from 30° C. down to 12° C. This morning
we had rain and fog...two days ago it was hot like summer.
Yesterday evening I've put the big heater from my show tank into
the outdoor tub to keep water temperature at least at 26° C
although it was below 10° C. outside last night. Brillant idea
because the fry are doing well this morning and temperature in the
tub is still 26° C.
It would have been a pity loosing 25 little fish because of a
stupid weather change. I add some sera micron 2 times a day as
some additional food. I only want to be 100% sure ;-))
- 29.05. - 25 L
tank : 30% waterchange, KH 3°, pH 7.0, 29° C.
Nothing very exciting has
happened, everything is working fine.
tub : waterchange 30%, 21° C
It has become quite cold
and temperature doesn't climb higher than 10° C. We have nasty
rainy weather. Therefore the water in the outdoor tube hasn't
become warmer than 21° C. at night. The little I. werneri are
swimming at the area where one of the heaters is mounted because
it's much warmer there. Clever little fish ;-) I'm feeding still
additional because I don'tknow what kind of plancton is living or
not at those temperaturs without sunlight.
- 30.05. - 25 L
tank : waterchange 30%
Everything is working
fine, no dramatic news
- 0utdoor tub :
Weather changed again,
now we've about 20° C. and the temperature in the tub is o.k.
As far as I can see most of the fry survived and have grown a
little bit. I think I will extend this experiment and put 25 more
I. werneri fry into the tub. The Tanichthys albonubes always
developed great in the tub without additional food but they don't
have problems with low temperature. So why shouldn't the I.
werneri develop the same if temperature is at least 24-26° C. ???
- 31.05. - 25 L
tank : waterchange 30%
I've noticed that there
are big differences in fry size. Maybe this is due different age
or the fry I caught out of the show tank were P. signifer. I'll
keep an eye on this because my feeling is they are Pseudomugil
signifer. They look a little bit different, are bigger and much
faster and....there are not many of that size in the tank....
- outdoor tub :
28 - 32° C.
I've put about 55 more I
werneri fry into the outdoor tub, now there are in total 80 in the
tub. I'm very confident that they will grow
well !The fry I put into the tub 4 days ago (!!) are much
bigger and darker than the ones I keep in the 25 L tank. They seem
to swim in in the middle of their food permanently. If they go on
developing like this in the tub, I will only keep about 30 in the
25 L tank and put all the rest into the outdoor tub. That will be
an interesting comparison and I'm extremly curious how big both
groups of fish will be in 2 or 3 weeks ! Btw...There are still at
least about 60 little fish in the 25 L tank which means there are
about 140 little fish in both, tub and tank. I'm afraid that there
will still be 60 in the tank after putting 30 again into the tub
I. werneri fry
