I just got this new baby axolotl but it was born in and kept in a higher temp at around 73°F until I got him about less than a week ago. The breeder I got him from said their 2 adults are perfectly healthy at 73°. The water he’s in now stands at about 70-73 and I was thinking about getting a chiller cuz they should be in colder but idk if this would actually be bad cuz he’s only ever lived in warmer? maybe he’s adapted and it’d be bad for him to live in cold? which is rly weird idk

i recently got a beta fish, he swam around all the time and now he just lays around. The only time he gets up is when i feed it and when i turn the lights on, i guess the lights just startle him. I looked online and what i read suggested that i get a tank heater, I wanted to ask before i buy. Do you have any recommendations?

Hello, I bought 3 fish (2 cichlids and 1 ray) and an aquarium (90 litres) yesterday. I prepared the aquarium and put the fish inside. However there is a power shortage at the moment. The temperature of the water is fine but what can I do to increase the oxygen level?

How to do clean water which fill in aquarium if doesn't have water conditioner?

Hi! I plan to move my goldfish to a 45 gallon, and I’m curious about what kind of fish dan go with them. I currently have a zebra danio with them in the 20 gallon I am currently keeping them in, but I found out that zebra’s require a heater while goldfish do not. And even though I have kept them together for a long time, I don’t want the danio to suffer. Another dumb question but would separating them cause anything, like anxiety for the fish, or am I just being a bit paranoid.
