I don't know if all fish do this or if mine are weird or what? I have noted my Guppies in the 25 gallon tank seem to really enjoy swimming in the filter current. They do it often but I have now noticed that on days when they are over there more, the next morning I notice babies. Anyone else notice their Guppies swimming "upstream" right before giving birth to fry?
In my 60 gallon tank, I noticed that my Barbs, Platies swim over the bubble stream from my sponge filter. When I am adding water, it makes bubbles and they all come rushing over to swim through the fresh water current. Even my Gourami seems to enjoy an occasional ride on a bubble stream and they are thought to enjoy calm waters. I don't know if fish learn behaviors from others regardless of species or not, but it seems like it in my tank.
I had to move 2 Guppies back to my 60 gallon tank. I don't know if that was the right thing to do or not but it was 2 males and they were aggressively going after other fish in the tank, including the Corie's. I dipped them out and put them back with the Barbs, Platies, Gourami and Rainbow shark. They seem to be happy as clams in the bigger tank. They just jumped right into the group with the Barbs and have even been seen chasing the Barbs around a little. Must be Psycho Guppies. Anyway everyone seems happiest where they are now.
Another behavior I always think is fun to watch is anytime I make any changes to the tank, the fish are so curious and go to the new object in the tank and investigate. Today, I had to remove a ton of plants and the clay pot. My fish had little room to swim since the plants were getting so thick. I downsized by half, it seems and the fish are whizzing about the tank with huge smiles on their little fishy faces. They all seemed to take turns going and swimming around where the pot was and staring down at the substrate. I wonder what they were thinking?
Anyone else have any goofy behaviors you might like to share?
