did somebody say plants????!!!!!

yeah i can def help with plants for that kind of tank.

but... seahorses and pipes are something i am also familiar with. i have never had seahorses but thats because i cant afford the equipment to keep them. anyways def no pipes in that tank way to small. and if you are adding horses to that tank you are limited to the dwarf ones, they will only get and inch or two. heres a link to the horses im talking about. Seahorse Source - Hippocampus zosterae

make sure you do some research on the horses too. they are trickier than most would imagine.

good plants for that kind of tank would be anything that doesnt attach well and if it does attach well it must be a slow grower. tree halimeda, mermaids fan for sure ( horses and pipes love to hang on to it), shaving brush, if youre getting good light you can do some red macros too, botryocladia. the plant world is very diverse. let m know i have many macros, i love mocros, and i know of many more than what i have currently.
