Hi,
I am afraid I may lose my little randy

.
Since I have had him I just cant get him to eat, I have tried
betta food, normal flake food crushed up. live blood worms, live
brine shrimp, mosquito larvae, soaking food in garlic juice, everything and he just wont eat. Now he has started sitting at the top of the water and not moving.
Water is 0,0 5 and I do 10% water changes every saturday. There are live plants in the tank and a slate cave so I dont think its that he hurt himself. Could I just be unlucky and have picked a betta that was on his way out when I got him? I picked him because he looked very stressed out in the tank he was in and was flaring at every other fish in there (he was stocked with about 20 tetras and not in a seperate cup)
I really look forward to you advice and hope I can make things better for the poor guy

.
