Off Kilter

Things in the fish tank are off kilter. One of the Black Widows has fungus and is understandably distressed while the Swordtail population has decreased to just three males which is too few to keep the hair algae under control and it’s growing like nobody’s business. I’ve treated the Widow but not much I can do about the algae without adding chemicals. I’ll maybe go searching for new algae eaters instead.
