My tank is only 2 months old, and i am sure i was going too fast, but everything was going so well maybe i got ahead of myself.
135g total volume, cycled ammonia after a week, nitrite after 2 more, gave it another week to be sure. Got 2 clowns and a shrimp 2 weeks ago, eating and doing great. 10 coral frags.
over the last 4 days added a small yellow tang, firefish, royal gramma and 2 banggai cardinals.
Everyone was doing amazing, fish and coral. But the gramma hid right away. He was our favorite and we would be so happy when he would come out from a rock, but soon dart back. Today i noticed his tail looked a little ragged. wasnt sure if it was aggression, or they have short tails. Then i saw him on the other side of the tank where he doesnt normally hide, and the tang took a nip at him and he fell over. he is currently alive but obviously dying.
so number one i am bummed because i was in charge of his well being, of course. But number 2 i am worried for the rest of the fish, and 3 i do want a RG but dont want to hurt another one.
Any ideas what could be the problem? was this fish likely sick when it got to the tank, did i mess up acclimation, is it possible the tang was aggressive?
specs:
115g display, 135g total 4ft.
temp 78
salinity 1026 (store was 1022. half hour temp acc. half hour drip acc.)
ammonia 0, nitrite 0, nitrate 5.7
phos 0.07, alk 7.3, calc 390, mag 1470
let me know if i missed any tests
rest of the tank: all coral are thriving, puffing up big during the day
fish are happy, active, everyone is eating. just starting to recognize when i am about to feed them and run up to get food (except the gramma)
everyone looks fat, no sign of skin disease, no tattered fins except the gramma. they are getting more comfortable by the day and starting to hang out in the front of the tank
filtration
- reefmat
- small chaeto refugium
- some temp filter floss just to catch sand and stuff from when i first set up the tank
- will add skimmer when bio load increases
feeding: quarter of a small cube of mysis (the kind that comes with like a dozen cubes per sheet)
occasional flakes. one sheet or nori every 2 days for the tang, and 2 sinking vegi tabs. (but he seems to eat mysis too)
stocking list
2 young clowns. she is about an inch, he is less than that
2 banggai cardinals
firefish
young yellow tang
coral banded shrimp (have never seen him mess with any fish)
no real CUC because i started pretty sterile with dry rock, dosed bacteria and ammonia etc, will add when i see algae.
i have a picture of him now but honestly its just depressing not sure what sharing it would do.
thanks for any advice you guys can give. And edit, by this time he is now gone. I cant reach him he is under a rock and the rest are picking at him. sad face.
