help me something is fishy in my tank

[bugattilambo]

Hi guys I am back there is this problem which came before chinese new year

I fed my fishes and seahorses with mysis shrimp soaked with garlic guard and that night I notice my big star fish moving its arm and didnt take a look but the next day I woke up, the whole star fish was kinda crushed with small little hard white stones nexts to it most probably frm its body . my other small starfish strunk in size

one of my nudibranch also died. the funny thing was I could not find one of my blue damsel and one of my nudibranch . All I had now in my tank was a blue damsel and seahorses,when I came home from cny I found the only damsel dead lying on the sand bed but never expected that half of the damsel body turned black

what is wrong I have checked my nitrite but it was not the problem

my seahorses are still in the tank.

U've checked ur nitrite only? Wat bout ur Ammonia, N03(Nitrate), PH and Temp?? How long did you have ur tank?

check all parameters and do a water change

every thing I tested was normal I have my tank for about 6 mths

is there something in my tank killing them?

thanks

The dead nudibranch or star could have released toxins that killed the rest. Another possible reason is the ammonia/nitrite spike caused by the massive die off of livestock. Do a water change quick.

Also let us know the capacity of the tank, filtration method, other livestocks in the tank or any other information that could give us a better picture.

Oh, the starfish wasn't crushed, the white stones could be debris from the dying body. Starfish would appear to be melting when they die, and slowly disintegrate. Most often, this is caused by bad water parameters. The disintegrating flesh will pollute the water especially if it is housed in a tank with small water volume. I kena before, marble star was eaten by bobbit worm and slowly died off... I stupidly left it inside thinking the disintegrating legs will grow back, the chain reaction caused by the rotting flesh nearly crashed my small tank

Please never buy LS on impulse. Think of the long term.

Hmm.. If tank has been running for 6 months, water parameters tested normal as claimed, then by right there shouldn't be a case of sudden death across species leh. Unless it's parasite or predator -- if so, then good luck
