fishroom build and 800 gallon tropical pond

Hi sorry not been posting ive been busy working, cheers for the advice about filling the holes i forgot to mention in my last post il give it a go. So not loads of progress pond wise but the fake rock wall around the pond has started, ive used all the used wood from the mould to make the frame for the rock wall which wraps about 60% around the pond, it doesnt look nice at the moment i need to buy more spray foam to fill the gaps and give it a rocky effect, ised used all the same techniques as i did on the waterfall but its bout 8x bigger so may take a couple of days, il upload the pics as soon as its done on saturday, i just need to buy a few more bits of ivy and pothos for when its done, then i have to pour the concrete floor then paint on the liquid rubber then hopefully fill it up. Im aiming to have a couple of fish to cycle the pond in by the end of november, then build my breeding set-up!

Cheers thanks a lot, heres a quick video of my pond, its only short i cudnt upload the long video, its just george the giant gourami (he was called that when i got him) and my dog elly, elly usually licks his head. Il upload that video tomorrow

The videos from a few months ago about 2 months after i got george and he was in a bad state, he had fungus on his scales and really bad finrot, so i had to take him and he went in this quarantine on his own for 2 months on lots of meds but hes looking great now his tail has grown about 2 inches and is almost perfect and his red has come back, hes just a bit old and grey now.

Yeah george is getting big now, he was really underfed but putting on weight now. So ive almost finished the rock wall now, the first two coats of cement is on i just have to add a bit more to get rid of any straight lines but il let it dry a day so it doesnt fall apart because of the weight of cement on a flat wall is causing it to slump a little. But so far so good il upload the finished pics tomorrow when its all planted and covered in moss
