Ok guys my rbta split into 3 about 2 months ago and moved around quite a bit and have settled, their mouth parts formed and have started feeding again, the 2 bigger guys decided to live on my back glass way at the top where water level is, where the main pump inlet is and boy do they get blasted, i have to turn off sump just to feed, below them on a rock is my purple tip is he the cause for my rbta not coming down, they were near each other for a while and everybody decided to move house together.
