Need Help

[Rukas]

I have a 3 x1.8 x1.5 feet tank

stabilized for about close to a year now

My stock

1 BT

2 YT philipines

5 Damsels

1 Cardinal

1 Clown

1 Hermit

3 turbo

REcently added 1 Brown Octopus, 1 green Buble tip and a Gornio and a crocea clam

I have also upgraded to MH ( 2x150W) and 2 t8 bulb(blue)

Now, everything seemed to be fine with the tank, until my YT, which was healthy and feeding( very active) died, close to my Bubble tip anemone

I have also noticed slow movement from the Turbo snail, they dropped off once and 2 had died, 1 still alive

Water parameters are all good including Phosphates, nitrates, nitrite, KH, calcium etc

water change bi weekly

PH: 8.5

salinity 1.023

Few questions i need help with

1. Could it be that my YT got stung by the anemone?

2. What could have been the problem with the death of turbo snails? could it be anything related to the MH?Been doing alright in my tank for many months

The only new occupants were the bulb anemone, brown octopus, crocea clam and the MH setup

anyway the Anemone is still not very happy with the lights, i am just turning it on for few hours a day to get the corals to get used to the light

the octo and Clam seems to be very happy

You have a brown octopus?

I assume you meant octopus coral - euphyllia paradivisa.

I can't draw any conclusion from your post but addition of livestock should be done in small quantities with a week or more interval.

It could be that your new introductions came with pathogens deadly to your yt and snails.

I hope so...

Yes yes, i meant the Coral, sorry for the confusion wont dare keep the brown octopus

Bro iskay, thanks for the reply, does this mean it has no logical sense to blame the Anemone and MH?

The only thing i didnt check was copper, but i use a RO-DI unit, not from Tap and i didnt perform any medication

If it were the anemone, it would have consumed or partially consumed the fish. If the fish were to scrape on the anemone and escaped, you should have observed wounds on the fish body.

Light change can be a factor as sudden change in brightness could have over-stressed the fish.

Like what I said, the information on you post is insufficient to derive any conclusion.
