I never thought anymore about it until a couple of weeks ago when I noticed a very small sid swimming around the rocks in the tank, on closer inspection there were at least two more about the same size. These small sids are under 3/4" which is smaller than any of the 36 that I originally bought and none have been added since, me and the wife did a quick head count and both counted 38 sids which is obviously more than I started with.
This is the setup that the Sid's are in:
I have now removed most of the decor and done a definite head count and from the original 36 I now have 42 Sid's, so that's 6 young that have survived
The spawning took place after I had added 7 shredded Indian Almond leaves, the ph in that tank usually sits at around 7.2 but did drop to around 6.8 with the addition of the leaves. The temperature of the tank is pretty much always 79.4 to 79.6, nitrites and ammonia are 0 and nitrates usually sit at around 5 to 10 ppm.
These are the first 3 photo's that I got:
(I used a macro lens for the first photo, hence the detail of the java moss )
I have managed these photo's over the last few days:
This photo gives an idea of size of these young fish, the Puntius gelius in the picture is just under 1"
The larger Sid's in both of these photo's are the smaller adults at just under 1 1/2", the young ones keep well clear of the bigger fish
Obviously there have been rumoured spawning's before but as far as I am aware these are the first actual photo's of young tank bred Sid's, but regardless of this I am very very happy to have spawned my favourite species of Loach
Job well done
