hi all im alil concerned about my rapheal catfish ive had him for close to a year now , and at first he used to eat like a fatkid on cake , and was grwoing nicely for the first 2 months i had him in a 29 gal tank at first and then moved him into a 55 gal tank but now he barely eats from what ive witnessed he eats about once a month if that and has not grown one bit im not sure if that is normal for the species but i am really fond of him and would like him to be healthy , so should i transfer him back into the 29 gAL to see if he comes out to eat more ???? any tips or suggestion would be greatly appreciated do you think he has parasites or something he doesnt seem to be sick but im confused at this point than ks in advance
