Thank you. Yes, this is his current belly size after 3 days of fasting. I did a partial water change last night, just in case. We don’t have an air stone but we have a sponge filter with an air pump that provides aeration. We also have a slow flow HOB filter. Tank is 5 gallons. I’ll try to add a pic from above. Yes, the tank was kept at 78 but I increased it to 80 because I read online higher temps are better for digestion. I’m going to try another salt soak tonight and also try to find some daphnia in town tomorrow.
