Ray are sensitive

[SENCH]

I found that rays are very sensitive when I did a water change.I scrubbed some of the aglae on the bottom of the tank.The ray will stop eating for a few days if worst the ray will rip.So far I hav lost 2 motoro and a sakura,left with a 12" mm.Hope bro will give some suggestion on how to prevent this from happened so that I could have a clean bottom tank.

What are your water parameters?

The ph is ard 6.5 to 6.8.Dun really check the ammonia and nitrates level,water change once a week.There is a red with the mm in the same tank eating quite well.

normally if i scrub the algae, i'll do 20-30% WC immediately after. no fatalities so far ...

maybe u can elaborate how u do it..

could it be linked instead to the water change? anyway my rays used to have this habit also.. they won't eat on the day of the water change.. guess the water change spooked them.. but they'd be ok the very next day.. so it might be the water change.. how are you doing ?

I will scrub the algae in the tank and do a wc 25%,then I add in chlorine and top up water with slow flow rate.

Now,I dare not to scrub the tank,fear I may lost my mm.The tank at the bottom is dirty I am afraid of having high ammonia if I scrub it.

I don't scrued my tank, i only use a sucker fish to clear the aglae. And i do water change of 20% Two time in a week. So far so good...

Bro, I scrub mine once a week. So far no problems...........Maybe u want to intro some aglae eaters like suckers into your tank.

4 rays for once a week water change might not be sufficient. check your nitrate level. i dont dare add suckers as they might be the culprit of killing the rays instead
