Sorry for such a delay...been running with the grandkids...Both Bettas are doing great. my 20 G has the crown tail 4 neon tetras and a mystery snail. The fifth tetra I found dead last week. Have no idea what happened. My 10 G my betta has been acting weird after he eats. almost looks like swim bladder. So I've changed the tropical food to pellits every 2 days. my 5 G I have 1 platy and 1 mystery snail. The snail is acting strange i'm thinking the platy is picking on him. How are you doing?
