I have 3 Zebras 1 male and 2 females.The mail has pair up with one of the females and they chase the other female when goes close to there favorite spot.I have in the tank some tubes but the pair preferes to stay under some cavities of a piece of wood i have in the tank.
No sign of eggs yet but yesterday i took some pics and i show the belly of the female to be swelled without eaten anything?
You can check the following pic.The female is on the wood.

Note that currently i am simulating the dry season.The water level is dropped,peat moss extract is added,filtration has decreased and the chemistry is 90% as rio Xingu.....
Please tell me your thoughts!
