I have a tank with fancy guppies and another that is used to grow out the babies. I have had trouble with moving the pregnant moms to the grow out tank to have the babies, they tend to get really stressed out and don't drop for quite a while. I was looking to put some good plants in both the big guppy tank and the smaller (grow out) tank. I'd like to leave the pregnant females in the big tank until they drop and then grab the babies out, but when I tried it last time, most of the babies were eaten by the time I got home from work. So it needs to offer protection for them. The only other necesity I have regarding the plant is that I don't want little pieces of the plant always breaking off and floating around the tank. So, any suggestions on what would work the best? thanks
