I received a Mala wolf fish 2 days ago and he was perfectly fine: eating like a champ, swimming comfortably, and breathing fine. This morning I discovered a crack in the front right side of the tank he was in. Long story short I transfer EVERYTHING including substrate, plants, and rocks and placed them exactly how they were in the previous tank and siphoned all of the water into the new 40g and did a 15% water change. The water parameters are 0ammonia, 0nitrite, 20nitrate. Only other tankmates are my marble goby and a redtail cuda both slight larger than the Mala. Both other fish are eating but the wolf is clearly more stressed and has already jumped out of the tank once. Luckily I heard it and ran in to put him back in the tank. And currently as I’m trying to sleep I can hear him smacking the lid of the tank. Also hasn’t touched or shown interested in food which seems out of the norm considering his appetite and aggression the past 2 days. Also breathing heavily, not TOO rapidly but more labored breaths than from what I’ve observed since I’ve had him. I dripped the other two, but the Mala was just floated since I didn’t have a third siphon. Could the Ph have been different in the bag vs tank? The Ph in the tank is 7.0 and he was in the bag for almost 2 hours. Or could he just be stressed from the move/ new environment? Any help would be greatly appreciated, I don’t want to wake up to a dead wolf fish.
