Low tech planted tank aquarist. Got started January 2018, love the hobby. Saving up to start a 125 gallon hitech iwagumi setup.
Patience is probably half the challenge of this hobby. Also research and money haha.
Java moss, ludwigia repens, hornwort, anacharis, there are more but I forget what they are called
The pet trade gets a bad rap for exploiting wild animals but sometimes the opposite is true.
Modern advances in technology affect every industry - even the aquarium hobby.
If you are looking for a unique invertebrate to add to your saltwater tank, consider the sea urchin.
