I have 1 African dwarf frog, and I have been trying to get him a friend for a while, because I know they are very social. in the meantime, I just put my hands in the tank and interact with him, about ten at night for social interactions , because they are nocturnal. he lives with 2 honey gouramis, which leave him alone, and 6 cardinals. I was going to go and buy him a friend today, but the shop are out of stock and I am going on holiday for 5 days, and I am worried or get too lonely and die as I know it happens. my friend, who is feeding them, he doesn't want to spend half an hour at ten at night playing with a frog. I have checked other shops near me, but no one has them. what do you think I should do, I leave in 2 days
