i read on this forum that cooler water is best for plants i would like to know how cool can a tropical tank community be and be ok for the fish my fishes health comes first thanks for any input
 
I have no idea about plants per se, but I know that cooler water dissolves more gasses (like oxygen and carbon dioxide) so it's better for everybody.

It also inhibits the growth of bacteria and other pathogens. And with the extra oxygen, your fish are better able to fight them off anyway.

I've heard on here that people should keep their tanks in the low range that their fish require, usually 74,75.
 
i don't remember where i read it would 68 degrees be too cold for cories plecos tiger barbs neons
 
I have all my tanks set at 72. I have all kinds of community fish.I have the following:

Angelfish,bushy nosed pleco, harlequen rasboras, bubblebee platies, Black chin,panda platies,dwarf espis,boesmani rainbows,tiger endlers, hifin mollies,mystery snails,assassin snails,yellow shrimp, red cherry shrimp,tiger shrimp.I used to have glo-light tetras in the tank but since rehomed them. All the fish I have are doing well even though some are used to warmer waters.

I also have a planted tank with low-light no C02, Black sand mixed with eco -complete, and pool filter sand that I put plant tabs in some plants.The plants I have that are doing good are:

Wisteria, Java fern, Java moss,Taiwan moss,Wendelov fern,Willow leaf hygro,Anubias,Dwarf sagittaria,Water sprite,Vallisneria, Spiral vallisneria,Cryptocoryne wendii red,Cryptocoryne wendtii, dwarf sagittaria, Chain sword. Some of these plants melted at first from the roots being tampered with after buying them but came back ok after I cut out the melted parts.
 
I generally keep most of my aquariums (12) in the 68-72 temp range except for the all black fancy guppies. The growth of my plants is slower with the lower temps but the fish are very healthy and maintain hearty appetites. I even keep a colony of of dwarf platies, including fry, at the lower end with good results.
