I went to go check on my ants this morning and noticed something weird, the water in one of the test tubes had changed colors! The water had changed red/pink! I held it next to a test tube that was just as old (both from mid April)
If anyone knows what this is please let me know. And if it's harmful to the ants inside I'll xfer them asap. The ants inside both tube are S invicta.
