30cm*12cm*17cm/1000=6.12 liters

Too small for any fish.

So, let’s do the physics:

30cm*12cm*17cm=6120cm^3

1 litre = 10cm*10cm*10cm=1000cm^3

Now that we know that, divide 6120 by 1000 = 6.12 litres.

Answer: your fish tank will hold 6.12 l of water.

Now, moving on to the aquatic side:

Each moderately sized fish should have 1 lite of space each, so you could fit 6 fish comfortably in your tank, and have space for 3 more!

That’s roughly 28.7g, or 109.7l. Minus the weight of the gravel/sand and decorations, minus a little bit of space at the top, so around 23-25g.

Dwarf lionfish grow to be around 5-6 inches, so nothing under 45g is recommended. Snowflake eels grow to be around 30″, therefore they are highly unsuitable for your size tank. Something around a 120-150g would be better in the long-run. Rectangular triggerfish grow to be around 10-12″, therefore a 80-100g tank would be more ideal.

Rethink your stocking ideas.

25 gallons. More like a freshwater tank for guppies than a saltwater tank for any of your listed fish. You need at least three times that size for your triggerfish. They get a foot long. What are you going to do when the fish tries turning around in that tiny tank and gets stuck sideways because its too big?

assuming those are inches, it would be a conversion of 1 cubic inch = 0.00432900433 US gallons

and you have 6120 cubic inches. So that’s about 26.5 gallons. Of course, you’d probably need to leave to space at the top, so maybe figure 25 gallons at most and maybe even as few as 22 gallons.
