Hi, Sharing with all some photo taken using Hydra 30 Filter to keep Altum Angel. This few pieces of Altum angle are not stable when it arrived. They are of different batches thats why you can see the difference in sizes.
We separate them out and place it another quanrantine tank using Hydra 30 Filter. And to our surprise, they starts to stable down and the water Ph is around 6. Since then, they are happily living for nearly 2 months plus. Sorry for the lousy resolution as they are being taken with handphone.
