In Memoriam
So of my ricordea garden (15 yumas), about 6 months ago 4 of them went white, then melted away. (as in the pic)
There have been no problems since the loss of those 4, until now.
Within the last weeks, 2 of my rics (bright orange and bright pink yumas) have maintained their brightness, but have begun to melt away. I don't have my camera handy, but it's standard melting -take my word for it.
My speculations:
1) Unrelated incidents, bleaching due to ?, melting = suicide
2) 1 particular thing caused both sets of losses
3) Recent zoanthid-nudi crisis. Used daily Rx dip, followed by rodi freshwater rinse, then back in tank. I don't think zoa-nudi's affected my Yumas, but i'm just putting it out there.
4) Montipora are growing like mad. I use biopellets. Most zoa colonies are growing steady 3-4-5 polyps per week. (20-30 polyp colonies), BUT, their colour has gone a little dull (i'm comparing pictures), i'm thinking maybe my water is too 'clean' ie. deprived of nutrients Yumas need. (I don't dose anything at all.
Tank Specs:
27 gallon display, 20 gallon sump
20'' tall tank, yumas on th bottom
light/medium flow
no other coral near them
Creatures:
Rest of tank or montipora encrusters/creepers
zoanthids
duncan
1 maxi mini
Flame hawk, sixline wrasse, cleaner shrimp
Water (unchanged over the last year):
everything perfect
no nitrates, no phosphates
salt@ 26 (Royal Nature salt)
**Just realised I can't post pics from my own computer. I'll post them online and then here tonight. (no access to facebook from work).
Thanks for the help!
