I purchased 10 of these in September 2012. I put them into quarantine in a small 30L tank with Java moss. 3 weeks later I had fry. So I moved the adults to my 4ft tank and started raising the fry. The fry are now just over 5 months old. Very slow growers. My adults are down to 5. 2 died from some sort of wasting disease, one got stuck on my filter inlet during the night and died and the other 2 just went missing. Im in the process of transforming my tank into a species only tank. Cant wait to have a 100 of these in the 4ft.

    They bred in the quarantine tank?  That was good luck!!

    I bought them in Cape Town and drove them to Port Elizabeth (about 9 hours drive). Then into the QT tank. I think possibly the change in water conditions as well as having a plant to hide in helped with the spawn. I estimate that there are about 20-30 fry. i lost a few as I was unprepared for a spawn. At the end of March I want to move the fry to the 4ft and try and spawn the adults again. Initially there must have been about 40 - 50 fry. They were tiny.

    My adults have spawned again. I lent them to a friend to see if he could encourage it. He now has about 50 fry. And whats more the fry that are now about 6 months old have spawned as well. Only 4 tiny fry. I think they are a bit young to produce many eggs but its an encouraging sign

    How long does it take for them to become full grown? I bought 6 online and when I received them they were only 3/4" and now they are around 1". They are all a golden color right now..

I’m far from being knowledgeable in the computer world but still learning. I’m uncertain on how to ask questions on this site. Can someone direct me to the proper way to navigate through? I have several fish and two large tanks and three small tanks and my favorite fish of all that I have are the shubunkins. I’ll get into details later when I’m able to submit questions. I enjoy reading the questions and answers especially about the shubunkins

I had a pair of these, I LOVED them!! My tank is heavily planted and they were always so romantic together. However my local water, even after filtration had a slightly higher pH than what is listed here and is harder and they did fine, very healthy especially when my tank turned into a jungle. However I decided to do a change in scenery and when I redid my tank, took out several plants, removed duckweed, changed filter, my nitrites spiked and they both died while the other fish survived. Even though I did a 50% water change, a week after the tank was changed. I didn't check water chemistry as frequently as I should have. They are delicate but well worth the extra maintenance. In the future, I plan to purchase more, I will be more careful.

    I am sorry. It is aggravating to go through so much work and have this happen. You sound like you know what you are doing though so keep it up.
