I know the carberryi's that SDguy and I both got from the same local LFS here have been eating like little piggies, so that part seems easy to me so far.
Time will tell on keeping colors, fingers crossed.
I do feed cylopseze fairly regularly, as well as PE mysis.
I haven't seen them take spectrum pellets yet, hopefully they start to copy my Lyretails.
So how long have you guys had them for? Did they come from Live Aquaria or LFS?
I feed mine the following:
- Hikari Mysis.... 1x daily
- Hikari Spirulina Brine.... 1x daily
- Combo of flakes: F1, F2, Prime Reef, OSI Spirulina.... 2x daily
- NLS Pellet.... 2x daily
- Live black worms.... every other day
- Cyclop-eeze.... every other day
They looked outstanding for a couple of months, but slowly lost color over that time (I wasn't feeding cyclop-eeze). Looking back at some older pics I guess there was a time when they were pretty pale. I have a really hard time capturing their true color in photos, but I'd say in any case they have always looked much nicer in person than in the pics, but definitely not like they did when I first got them... their color was so bright I thought I had a bucket full of ventralis or something! Here are a few to compare...
