hi, so my aro jumped or something and tore his tail almost fully, since that day he didnt eat and its been a week he is 7-8 inches . he is swimming with a 45 degree angle since yesterday im worried so im wondering if i should give him live feed which i dont like that much.
thanks

Give him a day or two. Leave the lights off and while monitoring him, leave him be. He just had a traumatic experience and is likely in pain.
