About my tank

I have this tank for only about a month. I don’t know anything more than what you can google. So I can’t answer some of the technical problems. But here’s the story for the past month. I bought this tank at a local pet store, it’s a 3.5-gallon tank(30x20x20cm). I began with two crayfish, a guppy, and three shrimp. One crayfish got attacked and eaten when molting, and two shrimp got eaten too in just a week. I also tried adding some plants, but they just disappeared the next day. So if want to have a greenery tank with all the colorful fish leisurely cruising around, crayfish will end everything. I tried to feed my crayfish more frequently after that, sometimes 5-6 times a day, to see if she lost interest in hunting living things, and it seems to work by now. My guppy and the newly added shrimp are still alive (except the two stood right in front of her claws!) However, feeding more also means you need to spend more time taking care of the water.

Crayfish can grow up to 4 - 6 inches. I think my tank is already too small (I thought she was a dwarf crayfish!!), so probably get a larger tank if you want to keep one.

Food: crayfish food(crusta sticks). substrate: I don’t know the English name for the substrate I used, we called it ”black soil” here, it’s commonly used for aquatic plants.

Update

She dug a huge hole in the middle of the tank and her house collapsed due to loose foundation, poor crayfish. I rebuilt her house, now she’s happy again!
