I got my betta maybe a week ago, he is a veiltail, he is in a Evolve 4 gallon tank and I will have pics of him, he is still mildly active, he has rarely eaten anything since i got him, I have tried Hikori betta bio gold, I also have tried crushing them up he just looks at the food never eats it, So I have also tried Tropical fish flakes I have seen him eat one single flake all week... I have done 2 25% water changes since I got him can anyone help me out im not sure if he is sick or just adjusting to his new home.
