Congratulations on your new family members they look great.
Sorry to hear you lost one all the best with the rest & keep us posted on how they are going over the next week or two.
Pups are still doing great, put the lights on today to watch them for a bit and they didn't seem at all phased. They're all adventurous and exploring every inch of the tank, at least two have eaten some squid pieces today and I'll be trying them on some blood worm tomorrow.
Pretty sure it's two males and two females I have.
