Nurse sharks are slow-moving bottom-dwellers and are, for the most part, harmless to humans. However, they can be huge—up to 14 feet—and have very strong jaws filled with thousands of tiny, serrated teeth, and will bite defensively if stepped on or bothered by divers who assume they’re docile.
The oyster toadfish’s scaleless, flattened body grows to about 12
inches in length.
It is a bottom-dweller found primarily within and around oyster reefs, in the Atlantic along the East Coast of North America, from Maine to the Caribbean. They are also found living among wrecks, debris, rocks, vegetation and other dark, secluded
spots in the shallows during warmer months.
The oyster toadfish feeds mostly on small crabs and other crustaceans but will also eat mollusks and small fish.
Yes, this debate is had a lot but I just wanna hear from you guys! <3
I’m soon setting up betta tanks again. I’m thinking of trying sand. I tried it briefly before and wasn’t pleased but am willing to give it another chance. While I love the looks of sand, I’m concerned about how messy it may be, as well as the ability for plants to take root. I’m interested in carpet plants this time around.
Flourite Dark, the clay gravel, is typically my go-to substrate. I was thinking of Flourite Sand or Tahitian Moon Sand this time around. Especially if I have a community tank with bottom dwellers like corydoras. I hear that the moon sand is a lot less messy to work with than Flourite but I’d rather hear it from other active fishblr members.
So I was planing on getting some kind of lizard when I get back from Australia but now that we are planning on setting up the 45 gallon when I get back(August-ish) I’m gonna shift my research focus to the fish for this tank. So…any community tank combos ya’ll would recommend? I would like a bottom dweller, a mid level swimmer “focal point fish”, and a schooling fish. My boyfriend requests a “cool” fish.
The oddly shaped head of a hammerhead shark is loaded with finely tuned organs called ampullae of Lorenzini, which can detect electric fields emitted by prey. Hammerheads use these sensors to scour the seafloor for skates and rays, bottom-dwellers that often hide in the sand. The extra-wide head allows for a larger number of electrosensors than other sharks have and may help these predators scan a large area more quickly.
Large schools of hammerhead sharks migrate hundreds of miles each spring and fall. The same electrosensory organs they use to hunt may also help them navigate by sensing Earth’s magnetic fields.

One of the reasons why you should have a big tank if you want to keep hillstream loaches even though they are “small” fish. This male refuses to back down from the alpha male s. spotted in the same tank which is why he has some “battle scars.”
Tank looks “cloudy” as algae is growing on the front glass also. Letting it grow until it covers all the other glass walls. Might be adding a Finnex Ray 2 to this tank to grow more of the green algae. Got an estimate on how much my dog’s surgery is going to be so may end up with extra.
