water temperature

I have a male koi plakat betta, in a 7 gallon cube tank with a filter, but without a heater. However, I live in a tropical country with an average temperature of 30 degrees celsius during the daytime, reaching upwards of 34 degrees during particularly hot days. I heard the optimal temperatures...

So it's hot here right now. Like... too hot (hot damn). And all day the tank has been hovering around 82-84 WITHOUT the heater on. And some of the threads say that's okay heat, but it's kind of stressing me out because I'm worried about it getting hotter than that. And my Mom said "Well why...

Hello everyone! I haven't posted in awhile. After my very first betta, Flo, passed I bought another female crown tail, Violet. Luckily she hasn't had any problems. A couple weeks ago I bought my first male, Claude. Three days ago I noticed three white spots on Claude which were obviously ich...

I have two bettas in individual 5 gallon tanks heated and filtered. I do 50% water changes every other day. Since I have my tanks at 80 degrees, how can I maintain the water temperature when doing water changes? Because wouldn't the temperature drop fairly low if I just use regular room...

Hello, I have a question regarding the water temperature for my betta fish. I do not use a heater and leave it in room temperature, and the thermometer in the water says it is usually around 75-80. However, lately the weather's been getting warmer and I noticed the temperature has been around...

Ok the worst possible thing is happening and I am freaking out :( Cosmo, the betta fish at my school is still there and school wasnt opened today and wont be opened tomorrow. ( His bowl is a 1.5 gallon until school can get enough money to buy bigger bowl/tank and has no heater ) Although his...

So Balthazar's water temp is currently at 74 degrees F, and I'm not sure if I should use my heater because it says on the package it could raise the temp by 6-10 degrees and I think that my be too warm, and especially since he's in such a small tank right now (3 litres, but I'm waiting on a 5...

I read on the care guide the water temp should be between 78 and 86 degrees. I was just wondering is 88 too high? That seems to be about the max temp I get with the heater I have. I haven't gotten a fish yet cause I wanted to see what my heater does. I don't know if that 2 degrees is just...

Hi there! I have two bettas and they live in a bowl and a tall vase without any kind of heater. I used to have another betta that lived for three years in a vase without a heater. My question is, do I absolutely need a heater? And if so, do I have to buy a tank for them that has one? What should...

I've heard that bettas are sensitive to temperature changes - within "a few degrees" - but what does that mean? In a large tank, the water can vary by a couple degrees in different corners that's OK, yes? For example - suppose your betta is in 79* water and a disaster happens and you need to...

Hi! I live in Texas where it gets very hot in the summer time ( up to 110 degrees) but its winter time here now and I usually keep the temperature in the house @ about 73 for it to be comfortable for everyone. I was worried about my betta though, I know they thrive in warmer temps but to keep...

Hi Everyone! My husband and I just purchased our first pet - a double crown tail betta named Max. Our habitat is a 2 gallon glass fish bowl (the standard kind with a flat front and back) with rocks at the bottom, a java fern, a small "ruin" ornament and a small bamboo stalk. We will be adding...
