Hey guys last Sunday I bought 6 glass cats for my tank. Since then they've been hiding (which I know is normal). Only thing is how do I feed them as my cardinals get the food before it reaches the bottom. I did get one glass cat eagerly swim to the top and took food a few days back. Just worried that I hope they aren't starving. Is there any way of delivering the food to them without the cardinals getting to it first?
