Overview
Tube Coral Block is an underwater block in Minecraft Java Edition 1.21.4. There is no way to craft it; you have to find it and mine it. Its hardness of 1.5 makes it a normal, unhurried block to mine.
Anything below a wooden pickaxe breaks it without leaving a drop. Breaking it produces Dead Tube Coral Block. It stacks to 64.
Nothing on the crafting grid is made from it.
How long it takes to break
Tube Coral Block sits at hardness 1.5: 7.5 seconds per block with your fists, 0.25 with the correct netherite tool.
You are looking at 0.4 seconds on iron and 0.3 on diamond — the diamond step is where the time actually falls.
The block still breaks with a weaker tool, but below wooden it yields nothing at all — the time is spent and the drop is lost, which is the single most common way players waste a vein.
Efficiency adds its level squared plus one to the tool speed, so Efficiency V is about 2.5 times faster than the same tool unenchanted.
| Tool | No enchantment | Efficiency III | Efficiency V |
|---|---|---|---|
| Hand * | 7.5 s | 7.5 s | 7.5 s |
| Wooden | 1.2 s | 0.2 s | 0.1 s |
| Stone | 0.6 s | 0.2 s | 0.1 s |
| Iron | 0.4 s | 0.15 s | 0.1 s |
| Diamond | 0.3 s | 0.15 s | 0.1 s |
| Netherite | 0.25 s | 0.15 s | 0.1 s |
| Golden | 0.2 s | 0.15 s | 0.1 s |
Properties
Tube Coral Block resists blasts at 6, which usually is not enough when something explodes nearby. Light does not pass through it, and it emits none of its own. A single slot takes 64, the usual full stack. Being renewable, it can be produced indefinitely in one world. The block is tagged for pickaxes, and only that class gets the speed bonus; everything else mines at bare-hand rate. Broken normally it drops Dead Tube Coral Block rather than itself; Silk Touch is what returns the block, and Fortune raises the ordinary drop instead.
