Hi Ollie
Although I only want to have a CPD(I want to take some precautions. You see, my cat likes to fish a lot and he’s NOT afraid of water. He has already attempted on the life of my goldfish. Any advice on how to protect the aquarium from the cat would be highly appreciated) my friend has one. Well, he doesn’t use any artificial stuff afaik. He prefers everything to be natural..weed, rocks, hiding spots..everything. I don’t know about his current amount of CPD’s but it’s increasing ’cause he’s already offered me one. Well, Ollie, try not to use artificial weed, control the water temperature(it should be not too high) and direct daylight falling on the aquarium is favourable. And of course, ask some specialists. They will surely know, how to breed CPDs
Hope it will help you. Good luck with you fishes.
