My tanks been sitting dry after a deep clean after my bichir passed , I just want a few different opinions on what to do. My tanks almost been sitting for a week with nothing in it , and I was thinking today I was going to start cycling my tank again , it’s going to be strictly bichir in it. I’m trying to decide if I should do a nice sand substrate like I had before or just no substrate at all. I have only 1 bichir now who got shipped in. He’s hanging in my breeder tank till I can get this one cycled lol. And sadly I got gifted another one who is on his way. So I’d like to try and start getting this cycled for a few weeks before I have to transfer them
