Hi I have a male strawberry hifin platy and I think he might be blind.It all started when my dad told my stater and I that one morning he found hifin(the platies name) sleeping on the gravel. Our dad doesn't take fish keeping seriously so he poked at the glass. Surprisingly whenever Hifin sees someone coming or someone pokes the glass he doesn't swim away. He's basically the hardiest male platy I ever have had. He eats but he is always the last one to food. He's small and when he doesn't seem to be hungry he doesn't eat. He knows the tank really well and sometimes bumps into other fish. He's in a 29 gallon tank with five other larger platies and he is not scared of people. Water quality not known because I don't have test kits ( my dad thinks I don't need them ). Please reply as soon as possible. Thanks.:feedback::feedback::shark:
