Hi Tom 2600,
The rams in my warm plec tank grew pretty fast too.(Their parents were a large strain).I bred them at Easter last year. They are now 2 1/2 " long and 1" body depth.
My next project is to "inject" some more intense colour into the larger strain by crossbreeding with some more colourful smaller strains.
I have found that Ram imports from the breeders in Europe are often infected with internal parasites and treat all my new stock with either Flubenol ( very strong aeration to be used) or Levacide(Levamisole). In fact the parents of my large rams showed signs of Camallanus worms (a dreadful disease) a few weeks after I bought them. Fortunately they spawned before succumbing to the disease.
The treatments, available from vets or mail order vet supplies, actually killed the worms but the prior damage caused internally was too great.The problem with this disease is that when the red thread like worms are visible at the vent, they are adult ( have already caused their damage) and are expelling live young .I however had to treat all my tanks just in case there was any cross infection.
These treatments also worked for me when I bought a large batch of Sidmunki loaches, and found them getting more and more emaciated and dying slowly one by one.Since using the treatments as described on
www.loaches.com , they immediately started putting on weight and havent lost one since.
Good luck with your breeding. I have found the zm food range pretty good for the free swimming fry from day 1.
Regards,
Des.
