Temp needs to go up.
Worms are not the issue.
Good catch didn't even notice that post. Temp is way too low. 78F is the happy number but mine varies from 77 to 82. Depending on what you have 1.024 salinity is a tad low except for fish only tanks. Years ago I ran 1.024 but now always 1.026 sg/ 35ppt.
