Really not a fan of the ‘packed look’, but to each person their own. As long as the fish are growing as supposed to, and show no signs reflecting on the overcrowding, they are fine for the time being. Love the FRT though. All I can say is, your fish would get more out of a bigger tank, and you would get more credit and recognition for your collection if they were in a bigger tank. But yeah they all look healthy at the moment and I’m jealous of your FRT!
