Questions re tank temp increase in summer
Actually, my first question is - when does a member go from posting on the beginner aquarium forum to the general aquarium forum? Based on a certain time frame, comfort level ???
Main question - with the hot weather here the last 2 days, my tank temp rose from 77.2 to 79.7, an increase of 2.5 deg. My house A/C was on (set at 82 deg). Even with the cool night last night (house this morning was 67 deg), my tank was still at 78.5 this morning (proof that large tank parameters change slowly). Is the temporary 2.5 deg increase a problem? If so, I will have to lower my thermostat so my tank doesn't heat up based on the room temp.
Second question - with the higher tank temp, my fish are REALLY active. They are normally active, but they seemed happier with the higher temp. Is 77 deg too low for the species I keep? I tried for a middle of the road temp that encompassed all the species. Do you think I should raise it to 78-79 - isn't that too high for the scissortails and danios?
Recommended temps from seriouslyfish:
Gold Pristella Tetras 71.6 - 82.4
Scissortail Rasboras 73 - 77
Neon Dwarf Rainbowfish 73 - 82
Glowlight Tetras 75 - 82
Zebra Danios and Long-finned Zebra Danios 64.4 - 77
Calico Bristlenose Plecos 69.8 - 78.8

+1 to main question answer. My temps swing 2-3 degrees through out the day during summer months. Typically my water is set for 78 degrees.25 Gal - Tropical

First Question - I think the beginners section and, if you keep rarer fish, the subsections like "Predators" to be the only useful sections of the forum. The rest is filled with commonly agreed upon bad advice and posters on a superiority trip that "just want to help."
Main Question - a little variation in temp is no big deal. The species in the wild experiences far greater shifts on a daily basis. We actually create incredibly stable conditions, relatively. The issue more or less revolves around sudden shifts... rapid increases or decreases in temp of many degrees.
Second Question - More of a third question. As temperatures increase, the metabolism of animals increases... they do become more lively. Please note... the same fish, when kept only a few degrees warmer, consume a great deal more food. It all has to do with that metabolism! However, warmer water supports less oxygen than cooler water. It's all a fine balance.
Unfortunately, no two fish are exactly the same. Temp ranges for fish are more for people to berate you in hindsight than for any real value. In fact, in some cases, fish that are bred in farms and fish collected wild can live in totally different temp ranges... some that barely even overlap!
The key is to watch the fish themselves. If they are struggling, gasping... it's probably too late, and too warm. If your active fish start becoming sluggish, that's when you still have time cool them off a bit. If they start losing color or becoming very sluggish... particularly when they swim nearly motionless... huddled to the ground... they are usually too cold.Looks about 40 Gallon Tank

Thanks - I will continue to post in the beginner forum.
Thanks for your replies. Maybe for a few of the species, 77 deg was too low. I was mostly concerned with my scissortails, danios and 2 BNs. My fish actually look happier - even more active (my tank was lively to begin with), really moving around the whole tank. I feed every other day, alternating with omega one color flakes and veggie flakes , then dried bloodworms and daphnia.
I will keep an eye on the tank temp as the summer progresses. If I need to lower my A/C, I will.

I think the glass tops help keep a tank warm by limiting the outside air from messing w/ tank temp.
so in the winter-I use the glass tops to help keep warm.
but in the summer, since I keep a house warm (like you) I take the glass top off to get more air to circulate.
the negative of that is-more evaporation, but it doesn't bother me much.

The tank temp in summer was also the reason I went with the single bright LED fixture, as it puts out no heat at all on the tank side and almost no heat on the top of the fixture. My living room temp is usually higher than 77 deg, so I don't know if removing the glass tops would help. I also have a ceiling fan just off to the side of where the tank is. I run it nonstop from April thru October. I was concerned that it would cause a draft - guess I don't have to worry about that!

A bit off topic, sorry if I offend...
It gets "hot" in Illinois?...the weather, that is?....LOL...come visit me in southeast Texas sometime, maybe July or August ...we'll compare what WE call "hot" to what YOU call "hot"....
LOL just kidding gronlaura, but could not resist...I had no idea that residents of Illinois even OWNED A/C...or needed it...

Fish can tolerate swings in the temp of around 4F +/- The improtant thing is the maximum temp doesn't get too hot, or the temp swings do not happen in a short period of time
Increased temp can reduce the oxygen levels in the water so make sure there is good water movement at the surfaceIf you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.
