Who Gives A Fish Forums

Thanks for the suggestions, everyone. I did add a new almond leaf a few days ago, maybe that's it. I'll remove it and see if he calms down. The flow's pretty gentle, but I'll double-check.

Chalices are pretty adaptable, but it depends on the species. Some will fade under low light, others might just grow slower. What's your current PAR reading? Mine do fine at around 75 PAR, but anything below 50 and they start looking dull.

My Betta fish suddenly started swimming erratically yesterday. Water params are good, 0 ammonia, 0 nitrite, 5 nitrate. Tank is a 10 gallon with a sponge filter, kept at 78F. He's been eating normally but now he's just darting around like crazy. What's going on?

Also, consider your photoperiod. If you increased light intensity or duration recently, they might need time to acclimate. Maybe reduce lighting by an hour for a few days.

Could be a few things. First, check your alkalinity and calcium levels. Zoas are pretty chill but they don't like swings. Also, any new fish or inverts added recently? Sometimes a crab or shrimp can bug them. What's your temp and salinity at?


Agree with Buddy. Alk swings are a big culprit. Test ...
