Fast gasping

[hondaker]

Hi bros,

did a major re-scape yesterday night to accomodate a newly acquired seio.

However, after the re-scape, discover that my mimic tang and flame angel was like gasping for air, their gills show that they are breathing very very hard

Currently, the tang is still able to swim around and take in food, but the flame angel has become very lethargic, prefers to lay by the sand and rest.

What could be the problem? My 3 clowns and blenny doesn't seemed to be affected by it.

I'm sure its not Ich, since my tank is doing quite well for the past 3 months without any casualties.

Thanks in advance

If you are using a DSB it might be due to hydrogen sulphide release, which causes pH drop. If there are alot of suspended solids in your water it might be affecting dissolved oxygen levels. Increasing aeration or even dosing ozone should help.

my sand bed is only about 2inches avg

does doing more water change help in reducing the above mentioned gas?

thanks

Mix half tank water and new water and place all LS into the pail and let your tank settle for 1 day. Remember to oxygenated the pail and tank together.

just an update, the flame angel and chocolate tang are alright now

guess might be the sand that was stirred up got into their gills, irritating them a lot
