Introducing New Fish
I have just bought a new siamese fighting fish and a panda cory. I already have 3 cory fish in the tank and some white cloud minnows. My tank floats between 72 and 80, so I need to make it warmer for the Siamese fighting fish and if so will it hurt my cory fish and minnow?
I am new to all this so am a bit unsure.
Bettas and corys like it warm, white clouds like it cooler, but I think they would all be fine at room temp.

So the temp I have it now is fine?
Unless you really like to crank up the AC, or turn off the heat in the winter, I don't see a problem.
Keeping the tank away from windows, doors or vents can help cut down on temp swings.

IMHO bettas should be housed in a temp of no less than 80. 72 is simply way to cold for a betta and is inviting problems as far as the betta's long term health is concerned. White clouds are a temperate species and won't do well in 80. All fish to well in a tank that was a steady maintained temp. Are you saying your tank is at 80 during the day and drops to 72 in the evening??
Umm no it kind of fluctuates between these temperatures. The heater comes on when it gets to about 72/74.
My heater is set to 72, this is what I was told to set it at when I got the fish 2 weeks ago. I am a bit concerned as I have read loads of different things on the net that say they are ok at 72/74. My cory fish are thriving with the temp as it has been but now I am concerned as I dont want my betta getting ill or dying. Makes it worse that they are my year olds fish (even though I do the looking after lol).
I got told to set it at that temp but the person who told me to set it that way also sold me guppies as cold water fish (was a novice at that point, well still am) and the guppies died within a couple of days.
I am tempted to move the minnows to another tank and maybe setting the temp a little higher to be sure.
Different fish have different temperature requirements, although most of the commonly-kept fish do well at what many refer to as normal community tank temperature which is 77-78F. But as I said, some fish have different preferences, and when combining fish in one aquarium you must ensure that each fish species will be OK in the one temperature; you have to choose a temp, and the fish must be OK with that.
The Corydoras panda and white clouds are mountain stream fish. Pandas should not be kept above 79F, and white clouds are better below 74F, and at higher temps they show signs of discomfort and are not as active or brilliantly coloured. The pandas would do well at 74, so both these fish will work if the temp remains 72-74F. I don't know what species your other cory is, but most are similarly happy at the lower rather than upper ends.
The betta will not be in good health at such low temperatures as kymmie said. At the same time the corys and white clouds cannot manage well at 80F. The obvious solution is to decide which fish stay and which should be re-homed, and suit the tank to those fish that stay.
A comment on the fluctuating temperature. Many would correctly assert that in nature the water temperature fluctuates from day to night, sometimes by a few degrees. I know of some aquarists who replicate this in their aquaria, from say 78 during the day to 75-76 during night. But that is a very different thing than a fluctuating temperature more often and during the day and night. And it has to be adjusted for specific-temperature fish. Most of us have aquaria heated the same temperature day and night, and I have come across no evidence suggesting this is detrimental. Uncontrolled fluctuations of 8 degrees (72-80) is a very different thing and one that in my view is not good for any fish.
They are all doing fine at the moment. I am currently not in a position to purchase another tank etc so I am going to have to keep it is it is. I have been watching the tank and its been more like 74 - 78 fluctuating, it doesnt actually drop into the 72 or go up to the 80. The other cory fish I have are bronze and 2 pepper. They are doing fab as far as I can see. They are quite active (especially the bronze) then they lie on the bottom (as far as I can see sleeping) for a little while, then start again lol. My house is not a cold house so it takes a LONG time for the temp to drop to 74 anyway so it's not like the temp is seriously dropping and quickly iykwim. I am just worried about the Betta now, although seems to be doing fine, active and not gasping for air or anything like that. What do I have to look out for if it gets stressed?
Stressed fish appear un-natural. The longer we keep fish the quicker it is to notice signs of this. Fish that are in a cooler water temp than they prefer may become less active, sluggish, fins might be clamped a bit, may have less interest in food and things in general, sort of just sitting there or swimming lazily. They may be more intimidated by other active fish. Betta also must breathe air from the surface, so the tank should be covered to ensure the air above the water is moist and warm.
By contrast, when temp is too high the fish generally have difficulty respirating as warm water contains less dissolved oxygen and cooler water fish are generally more active so they need oxygen; these may become lethargic, spend more time at the surface, also not have much interest in anything including food.
Hi all, I'm just stopping by to put in my two cents. I've read a LOT of Betta keeping. Everything I've read says that they don't get along with most fish, and they need higher temps than most.
I've been keeping one for a month now in a 5gal with other fish, like Neons and Fantailed guppies. These are two fish I've read that should NOT be kept with a Betta.
The tank is in my office. Check my profile for pictures.
This tank is climate controlled by the temp in my building, so it fluctuates between 75-80F.
My Betta is doing fantastic. Sometimes he even schools with the guppies. Whenever I change something in the tank, he investigates it. He recognizes me and is very active.
I feel that these fish will adjust to what you do with them, within reason.
