📜 Backstory
A hobby staple carried by J&L Aquatics as 'Hammer - Toxic Green Branching' and by The Tank Life, with a 'Toxic Green Gold Stem Hammer' WYSIWYG variant sold by Queen City Corals. It is a common wild-type color form widely traded under the 'toxic green' label rather than a single designer line.
Keeper tips for this variant
Give it moderate blue-spectrum light to maximize the green fluorescence and keep flow gentle and indirect to protect the inflated tentacles. Allow space from neighbors for the sweeper tentacles.
