How to keep livebearers healthy
Hi everyone! It's been a very long time since I've posted. I wanted some advice on keeping livebearers healthy. I can never seem to get them to live very long. I think my record was a year, and I really think they ought to be living longer than that. I've recently bought some platies that have gone through quarantine and treated for possible worms and have added them to my 29 gallon planted tank. It's planted with lots of crypts, anubias, some java fern, and dwarf sag. The rest of my stock includes brilliant rasboras, zebra and pearl danios, and some juvenile guppies. The guppies are doing well, and I assume it's because they were born in the tank, but their mom has long since passed. However, I really want the new additions to thrive as well.
Tank gets a 50% water change every week and the only fertilizer I add are seachem root tabs. It's just a low tech, low light system, nothing fancy. So, what can I do to optimize my tank for my platies? Does gH or kH need to increase, and how can I accomplish that and how will it affect my plants? Any advice is greatly appreciated.
