My betta stayed at the bottom of the tank throughout the night. So, i figured he had SBD. Yesterday, I gave him two empson salt baths, and I had him overnight in general cure + furan-2 + kanaplex + methylene blue. Today, i changed his water and did a short epsom salt bath and then put him in his current methylene blue temp tank. I am afraid he wont make it. I added an airstone and increased the flow of air. He sometimes moves his pectoral fins more now that I increased his air oxygen. In fact, previously, before increasing the airflow, he did't move his pectoral fins but just lay on the floor. I think he might have constipation.
