hygger Clip On 24/7 Lighting Aquarium LED Light,Sunrise-Daylight-Moonlight and DIY Mode, Adjustable Timer/Brightness Fish Tank Light with 7 Colors for Planted Tank (14W for 12~20in Tank)

I exclusively use Hygger lights. This one is really nice for tanks with low/medium-light plants and emersed growth, but it’s not strong enough for very delicate and demanding plants. For my tanks with plants that need tons of light, I use this one. It’s extremely bright and so you can totally burn your plants, but you can adjust it! I’d personally stick with the first one and see how your plants like it first. That second like can be difficult, and I’ve struggled with algae real bad while I was trying to get the lighting dialed in. If it’s a crab-only tank with say, shrimp, be mindful of your hardscape. Tons of caves are lovely but if the crabs have tons of hiding spots, you’ll never see them lol. I try to make sure to have just 1 small hiding spot, and tons of other enrichment areas in the open so that they feel better coming out in the spotlight for me.
