This is just a quick journal about my pair of Matadi's 
They started out like this in a group of 4...
Then the pair I have now started attacking the other 2 so I separated them and re-homed the other 2. This pair then started to change in colour and shape. Starting like this...
These were taken about 2 weeks a go and they've still changed yet!
Had 3 batches of eggs from them but they've suddenly stopped breeding again. Guess they're just taking their time
I'll add fresher pictures when I can get some XD
