Absolute Optimum Temperature?

What exactly is the absolute optimum temperature for plant growth and tropical fish mix? I was thinking 78, but have seen people with it down around 75-76.

I have been keeping Comboda, Anacharis, Red Ludwig, and Water Sprite.

Fish are mainly neon/cardinals, various cory's and botia, etc.

any idea?

I think there is no such thing as optimum temperature but I know that most fish and plants will do fine around 76 but most people i know that keep amazon aquariums go a bit higher around 82

Absolute!? Different plants prefer different temps, most do well in the "tropical" range that our fish come from say 70-80'S. Ive had best luck fish wise around 78 so thats where I keep mine Im sure 76 is just as good Ive had problems with Ich going below 72 . I would base your temp on the fish and you should be able to grow most plants if other parameters are in order. My discus tank is around 86 and plants are doing good.

As freeflyer has said, there is no set "optimum" to go by.

Different species of fish will prefer different set temperature ranges, and different plants will prefer different set temperature ranges.

Best thing to do if you want to provide the best temperature for you fish/plants, is to work out each individual range and go for the value that satisfies them all....
Plants
Comboda? (Cabomba) = 22-28C (72-82F)
Anacharis = 20-24C (68-75F)
Red Ludwig = 20-30C (68-86F)
Water Sprite = 24-28C (75-82F)
Fish
neon = 20-26C (68-79F)
cardinal = 23-27C (73-81F)
cory's = 22-26C (72-79F)
botia = depends on species, commonly 24-28C (75-82F)
etc = unknown - no suggested levels for this species!

The only figure to please all the above perfectly would be 24C, as Anacharis prefers the cooler water and botia sp. prefer at least 24. However, this doesn't mean to say that the fish/plant will be stressed by a slight deviation from these ranges.

thanks for looking all those ranges up... is there a certain website you used for that?

I will stick with 78f for a while and see how that goes. seems like a good intermediary temp anyway. i used to have lots of discus so had the temp up pretty high. use-error however has declined the number of discus to 1 so I can please the normal tropical fish instead.

while on the temp topic though, does algea pop up more or less in cooler waters (cooler being < 82f)? or does temp really matter?

No probs.
I used my Aquarium Atlas; an indespensible species guide!

It does grow faster in warmer waters, though I am unsure as to how much difference a few degrees would make.
Algae is highly adaptable to conditions and would still survive, but perhaps appear at a slower rate with a lower temperature.

It may cause different types of algae to be more prominent. My tank has some red hair/fluff algae that is only a problem in the winter...when my tank is around 60-65 F. In the summer (temps around 70-75 F), I generally see more green alga and hardly any of the red.

Hopefully I'll see neither in a few weeks...once I figure out my new dosing schedule.

You never know... you might get it wrong and get a new type!
