so I got rid of all my platies, donated them to the LFS. now then, I was curious about koI swords. the LFS had three morphs and I can't recall the names off the top of my head. at 6$ a piece I don't want to get all three mutant strains and mix the genetic lines just to get mutts; a happy mix of the koI genes would be preferable. I kept some koI swords about 7 yrs ago and despite being in a well cycled tank they dropped like flies in my quarantine tank, which I knew was perfect, cuz I kept fry in there before and after. that retailer also stopped carrying them coincidentally. now I'm seeing them rise in popularity and wanting to try them again since I'm sure they have gotten stronger genetically and likely have better immune systems. any have good data to share on this variety?
