This is our freshwater, semi-aggressive aquarium. Currently, it consists of: 4 Tiger Barbs 1 Pictus Catfish 1 Rainbow Shark Previously, we had a Pink Kissing Gourami and another barb, but they both died (sadly due to water conditions most likely, but we’ve been monitoring the conditions more rigorously now). These are all the fish we have in there now, and when we move into our apartment we hope to add another fish or two. The aquarium is a 29 gallon, glass rectangle aquarium (stand and tank purchased from wal-mart). All our fish came from Pet Smart. We picked some of the smaller ones so that we could watch them grow up throughout the years. We bought all the decorations from Pet Smart as well- the plants are plastic and the log and shelter are both aquarium safe and I assume they are a clay product. The tank is cleaned regularly, and the carbon filter is changed monthly (don’t forget to do this!). The rainbow shark is certainly the most aggressive in the tank. Despite ample hiding places and his own shelter, he tends to hang around the catfish’s log and bother any of the barbs that come near him- as you can see in the video. He picked on the Gourami from time to time, but not often. He has never picked on the catfish, and seems to prefer him over the others. The Barbs are the most active. They stay up top most of the time, but come down to the bottom to get bits of food in the rocks between cleanings. They dart around the tank rather quickly, and netting them to move back from college for the summer was hard work. They are voracious and greedy eaters- if we just use flakes, they’ll eat them all unless we deliberately push some towards the bottom of the tank for the shark and catfish. Next up is getting some sinking pellets for the bottom-dwellers. The catfish is my favorite. He stays in the log most of the day as he’s more of a nocturnal fish as most catfish are. When he does come out (at night, or for cleaning) he’s the most majestic swimmer in the tank. When he’s out, he likes to swim in triangles on the side of the aquarium. It’s pretty fun to watch him doing this little deal. I sat and watched him once for 30 minutes, and he kept going after I left! He’s skiddish of fast movement when he’s out during the day, and he’ll hide in his log until the coast is clear if you move to fast. His spots and whiskers make him a very beautiful fish. Do not make the same mistake we did and catch him with a net! His barbs will get caught in the net and you’ll have to cut the net to get him out. We did this and he eventually shook off the net after a day or two. So this is our tank!
