yesterday me and my partner we chanded the water for our fish for the 4th and we notice that our is still happy and still energetic as alwys although last we were much concered about the behaviour because it seems like the fish did not want to eat the food but since the beggining of this week the fish is eating the food but now the problem that we notice is that is the fish grow bigger in size it finds a bit difficult to move around the tank since it seems a bit smaller so i suggest that maybe next they can but bigger fish tanks so that the fish can be able to move freely
