Warmer water killing California round ray?

[EthanD152]

I was reading some online about the lifespan of the California round stingrays and saw one person only keeping them alive for 3 years and others speculated it was due to him keeping his temperatures at mid to high 70. I keep mine at mid to high 70s as well since I don’t have a chiller. Does anyone know if this will lower the lifespan on my girl? And If so what temp should I do that my snowflake eel can survive as well . Thanks

I read they do best in 65 to 75 degree temperatures. There natural habit is 54 to 72 degrees. They can be kept up to 78 degrees. No experience with either but the best temperature for either would be between 72 and 75. Depending on where you live might be best too look into a chiller for the summer. I know they have some for under 300.

Probably fine if under 78 but might stress it out if warmer.

One of the few pages i read.
