About 10 months ago, I was lucky to buy 2 couples Parosphromenus tweediei. Their availability had been reported in this forum.
The first pair was put in a 20 liter tank. I hoped they’d start breeding soon. Unfortunately, the female seemed to be severely surpressed by the male. She was constantly hiding, or withdrawn in one or other corner of the tank.
That’s why I decided to accommodate the second couple in a tank with a young P. linkei pair that already had been arguing as well since the day I got them. The result of this unusual cohabitation was positive: it made the fish be more present in the tank, without visible problems. Despite of the fact that they hadn’t been able to live together as seperate couples, they behaved surprisingly well in a group of four :dry:
(P. tweediei on the left and linkei on the right)
(P. tweediei female)
After a period of 2 months, I isolated the 2 couples in separate tanks. Their attitude immediately changed. The tweediei male became very dominant and unfriendly towards the female. She was banned in a corner, in the same way as it had happened with the female of the first tweediei couple.
I never noticed the tweediei males trying to seduce the females. Nevertheless, I recently discovered several juveniles in a P. tweediei tank. I was shocked by their measure (probably more than 4 weeks old) and surprised that I hadn’t seen them earlier. Of course, I even hadn’t expected them to be there:
I’ve never seen the male guarding, or whatso ever but there are at least 5 juveniles, probably more. About the tankwater in the previous 2 months, I know that it’s pH was situated between 5,8 and 6,1, with a conductivity around 45.
There were finally 7 juveniles and since a couple of months, they are residing in a seperate 35 liter tank. The majority is definitly male, but there is one single fish whom I suspect (read: hope )to be female.
The pictures underneath show how their colours are developping. The biggest ones are about 8-9 months old. To allow futur comparison, I plan to post some other pictures when they are adult.
thanks for documenting with those fine photos. Its great to see off spring of these fish. I will be taking some photos of mine when they grow up. At the moment they are really small.
Thanks for the compliments.
You should have seen me, laying during one hour on the floor to take approx. 100 snapshots from the lowest tank on my shelf. If somebody would have photographed me, I’d finally have an avatar :silly:
These juveniles still look rather different than their parents. It makes me wonder if the different stages of the genetical evolution of a species is reflected by the way their fry evolves towards maturity.
