Let me see if I have the basics of this post. You want to grow out less then 10 two inch and three and a half inch discus in a 150g planted tank? Is that the correct number of discus and tank size? Good for you! Please keep SD posted on the results. I was going to try that myself but it appears to take a lot of work that I may not want to do and also a high degree of difficulty. Due to legal problems with my landlord I have my tank and set up ready to go. I will try for some new legal opinions from friends this week and hopefully start up during the week. I was going to start with 4-5-6 inch fish, depending on what Hans has when I am ready. It looks like no discus for me to at least Oct-Nov instead of my hoped for Aug-Sept. I am very curious about your results and I will read the old postings listed on this site.
