Hello guys, and girls. I bought a 2-3'' tigershovelnose last Thursday and I have had him for 4 days now. I tried feeding him wardley brine shrimp, wardley bloodworms, market shrimp but he hasen't been eating anything. Temp of the tank is 80 degrees. Tankmates are 2 silverdollars, an asian upside down catfish, and an oscar. What else should I try??
