are green terrors and large clowns incompatible due to temp

[djsaltynuts]

i have a green terror that im moving to a brand new tank that sits right above of my rooms heater usually my tanks sit around 74 degrees without a fishtank heater. green terrors dont appreciate temps above 78degrees so i didnt plan on using a heater in the tank. would mid 70s cause illness in fully grown clown loaches? im aware they like discus temps.

Both do well at 77. At the high and low for both, but it can work.
I doubt you’d be the first to keep them out of the ideal temp range.
Each would probably be ok on temps a few degrees into the others.

i have kept clown loaches at room temp of average 69-71 degrees for over 30 years and they grew to 7-8 inches and thrived,green terrors i have kept at the same temp and in the same tanks,i always have had clowns and red tailed loaches they are one of the best cleaners that really get down into the cracks of the large chipped slate gravel i use and they are my two favorite loaches,i also have a fat 8 inch tiger (botia) loach who has been living with my koi for the past 7 years and that tank is in the basement and stays right around 65 in winter and 68 in summer degrees and he thrives

pocono - this is fascinating, I've only ever heard of clowns thriving >28C. My clowns went very quiet last year in a storm where room/tank-temp dropped from ~26 to 21 overnight, though nobody else seemed to skip a beat. The clowns are currently in a heated 100 kept at a solid 26 - theoretically still on the chilly side, or so I thought.

There's very little info on the lower-end tolerances of our hobby-charges. Me, we're putting in a pond in the yard for the arowana & i've been worried about winter temps. We're @1600' & it often gets <18C (64.5) on a stormy overnight, particularly if it rains - back to 22+ as soon as the sun comes up. It feels to be erring risky for her, so thinking through rain-covers & a heater, as well as depth (5.5' at drain). However, only keeping/bumping to 21 should be very doable.

if you raised clowns at a constant 80 degrees there whole life and then all of a sudden one night they goto 70 degrees in a matter of hours then yes thats a problem for clown loaches(and most delicate fish) and that is called tempurature shock and while it wont kill them clowns dont like it much, but if your clowns were raised there whole lives at 70 degrees they will thive as that is what they are used to and its well within there temp range.
keep in mind when you see a website that states 78-85 degrees temp range for a certain fish, 99% of these websights are just giving the same info they read somewhere else on the web, very few websights do there own research (or even own fish they are giving info on for that matter)on what temps or water perimeters work for that type fish.

Absolutely. I'm interested in how quickly temperatures drop with elevation, and how fish from rivers may be far more tolerant than we're expecting. Reptiles also; anything that might err up a hill or into a desert night, it should be able to hack quite a drop. This may include a rapid drop overnight or a storm event, this may include chronic.
Having said that, apparently they had to re-introduce Chichla several times into Florida before they'd stick through cold pulses, and C.monoculus did far better than C.temensis even though they come from the same rivers (but where in those rivers?). (I met the guy how did the introductions through work maybe 20yrs ago). Neither took in Texas even though the temperatures were only vaguely lower. Maybe they should try again now that Climate Change is kickin'in properly - the silver lining
