Ruberto- thanks all my filtration is the same as in start of thread- many thanks for the compliments !
thanks guys an update is incoming quite a few changes had to frag the big monti it was taking over,
My female clownfish died but it was 100% old age she was with me over 18 years(id say over 20 years plus imo) and lived another 5 years after the last dominant paired female died and she became dominant female after changing from a male, the small male she was paired with is becoming a female - i have to keep an eye out for the mate (black saddle back) polymnus species
Also my cowfish is also on its way out it has for the past couple years developed a cataract in it's eye and is becoming blind in one eye now , also it appears to be having swimming problems after, a meal, i suspect changes to swim bladder and internal organs given it's age about a year ago i thought it was dead but managed to get it strong again so it is a fighter but time marches on...
