Advice needed urgently

[junwen1010]

I caught a grouper size around 16cm a few hours ago.. i went to bought a pack of marine salt 2kg(i think is red sun or wat brand). filled my 2.5*1*1 tank 90% full pour in the 2kg of salt. and i add in a air disc.. after about 30mins, i let the fish in.. for the first 10 mins, the fish kept opening the mouth wide.. i dunno why this happen... after that it slowed down.. now rest on the tank bed.. tilt abit beside le.. but eye still blinking and its still breathing.. can someone advice what should i do.

u mean the water u just pour the salt mixture staright away?did u measure the the saltiness using a salt gauge to measure the salt ?

recommend salinity shuld be from 1.023 - 1.025 ppm. you could also try aerating the water by placing in an air pump. however this is not a long term solution to sustain a condusive enviroment to keep grouper. btw groupers are known not to be much of a mover...they generally stay in 1 position could this be a reason for its behavior? and also if i find a fish that blinks...i'll probably be quite afraid. if you get wat i mean

You need roughly 35 grams (varies with brand) of salt per litre of fresh water to get a decent mix of salt water for keeping marine fish. 90% of your 2x1.5x1.5 tank is roughly 115 litres, which means you need close to 4kg of salt.

I'm guessing you don't have a hydrometer to measure the salinity of the water? Also, it is not advisable to add in a fish immediately after mixing the water, cos the salt and mineral may not be completely dissolved, appearing cloudy. The particles could sting the gills of the fish.

As for the air disc to aerate the water, it is probably not enough to keep the fish for long term.

wild caught grouper quite hardy but still yur salinity must be correct as adviced by bros here..... once u get it rite have a proper filter system to sustain the fish eg liverocks, or OHF... need proper system if u intend to keep longterm.... unless u intend to consume it .... pls do not introduce it to yur existing marine tank (if u have one) until properly quarantined....

thanx bro.. emm.. i've got no hydrometer.. but the packaging state the direction and amount to add in.. therefore after calculation i add in the salt and required amount of water...

omg.. i almost killed the fish.. but.. the fish looked healthy and very happy now.. lucky me.. thx...

yup.. got to think of some other plans.. and i not going to eat that cute little grouper.. haha.. thx..

i'll be afraid too if i see a fish blink

hi, first off... did you use a distilled water to mix with your salt mix? salinity meter is a must for saltwater hobbyist... thats the first most inexpensive thing in your tank that you should'nt miss, anyways, going back... you should have at least tried to aerate the mixture for at least 2.5hrs before you put in the fish to give the salt mix and the water enough time to blend... and another thing, at least give the fish some time to acclimate with the tank water temperature... at least 1.5 hours. how you do it? keep the fish in the plastic, then float it in the tank... keep the plastic closed (i assume you put some o2 in it) then after an hour, open the plastic, you can start mixing your tank water in the plastic slowly... and so on...

is the fish still alive today ?

Yup.. In my friend's 5ft tank...
