I have a leopard gecko and it seems that the temperature in the tank isn't getting to what it needs to be. I have a heating mat and a thermostat and i have the heating mat highest up to 93 degrees. But the air inside on the warm side is only like 79 degrees how do I fix this I know that heating mats are the best for them but it isn't making my tank warm enough. Also, I know that heat lamps aren't the best since they aren't basking animals. So what should I do to make it warmer?

My fish all have ICH and we have only had them for about a week. Our tank is at 70º and it is a 10 gallon fishtank with a albino catfish, a koi fish, and one classic gold fish. The gold fish is the only one HEAVILY infected! What do we do?!?! P.S we do have one live plant in the tank as well.

I live in Hawaii and was told that I didn’t need a heater for my baby beta fish. I still find my fish to be very lethargic and unable to swim properly. What should I do.

Hi, I have a marine fish tank with 4 fish, an anemone, and a couple of invertebrates. There's nothing wrong right now but I'm scared that I might have jeopardized the aquarium's safety during a maintenance routine. I was doing some aquascaping when I realized that I forgot to rinse my hand beforehand, which worries me because I had handled clorox wipes (benzyl ammonium chloride) roughly 30 minutes before touching the water. Are my fish going to be ok, and is there anything I can do right now?

My fishes are being soo Inactive. I've checked every, the temperature and all. Air flow too, but they are still inactive. They only get active when I feed them

Fancy leopard geckos need light. If I keep the red light on 24/7 as directed by, what should the temperature be?
