What to do with old tank

Looks like im upgrading to a bigger tank (380l Planted):bigsmile:


So I dont know what to do with my old tank (i dont want to get rid of it)

Its 110l I want to do something defferent with it (not planted) had an idea to do discus but after some research definitely a no go.

So any idea's from you guys?

What about a malawi tank??

Or a breeding tank of some sort.

Any idea's would be great!

 

Brackish tank! They're seriously under-rated!
I have a 1.2m brackish set-up with 2 mudskippers and 4 knight gobies. I have a F8 puffer too but he sadly died. Everyone else is thriving though and the gobies aren't very colourful but they're alot of fun to watch.

 

What about a sump for the 380L :bigsmile:.
