I recently realized that a platy in my 10 gallon tank had babies. There are currently 4 platys and 4 danios in the tank. There were 3 babies but now only one. The other two were flashier and I think they were eaten
The one that is left has been very sneaky, hiding under rocks, etc. - it is a dark grey color so blends in better with the substrate. I estimate it is at least about 3 weeks old now. My question is this - I am afraid the others will eat him(her?) so I bought a small 2.5 gallon tank and moved it there. It has an undergravel filter with bubble stone and I am afraid the current may be too strong for the little guy? It came with a 600 motor for the air. I did fill it completely with water from the bigger tank so hopefully not too big a shock (but I thought better than being a meal for the other fish.) Does the little guy have a chance to survive? I was torn between leaving him in the tank with the big fish who love to eat everything and letting him have his own tank and have a chance at growing up. Also, what is the ideal temp for a baby fish? I have it at about 76 degrees.
