Re: Temp
Dear Twinkle,
No problem on the help. I'm on here to give and get help in the hobby, so it's all good.
It's up to you which way you'd like to go. 19 degrees is closer to the ideal and shouldn't stress your axolotl at all (temps of 24 degrees upwards can be stressful, but yours isn't nearly that high), so you will probably be fine with that, but you can also let it drop to 14 degrees if you're concerned. If you do go down to 14 degrees, just be sure to lower it slowly so they don't go into shock. Once a temp is chosen, the key is consistency. They can stay at 19 degrees as long as it isn't constantly fluctuating.
Axolotls should have tummies as wide as their heads. If it's bigger, then the axxie may be a tad plump. Feeding every other day is a good strategy, especially lower fat foods such as bloodworm. I like to feed mail-order dendrobaena earthworms as a staple, but I'm not sure how fatty they are so I can't say if they'll suit your axxie's diet plans.
If you have an iPad or iPhone you can take pictures with the device, then select the 'attach files' option from 'advanced options' when you compose a reply. If it's a camera you may need to attach a USB, then take the pictures off. You can then follow the same idea using the 'attach files' option. Hope this isn't patronising, but I'm not sure how much experience you have with technology so it's easier to detail all the steps.
Hope this helps!
