Most aggressive/fun fish for an 80g

  • We are currently upgrading MFK. thanks! -neo
I agree with the Wolf Fish! Just got back from a trip to Denver where I saw a full grown male Dovii in a 180 gallon by himself. He was such a cool guy! VERY interactive- followed you back and forth and would smack at your hand if you touched the glass. He was HUGE and blue. Very much a "wet pet" to the owners- who tease and play with him often. I wouldn't put my hand in that tank though....cleaning day must be interesting!

I never knew dovii's was known as wolf fish lol that would be cool but I think the closest I could get is an oscar.

Yea in the post is said about wolf fish I was referring to hoplias species

I think you were on the right track to start with, I would go with a solo or pair of small to medium sized snakeheads. You can't find an easier to care for or more resilient fish and they are full of personality. Bleheri or other dwarves are very attractive, could even go a bit larger with something medium sized like Pulchra or Asiatica, both are nice heavy bodied Snakeheads but still suitable for that sized tank.

Added bonus is that most of the dwarf to medium size channa are subtropical, and do well in a low filtered heavily planted tanks , so no need for heaters or noisy blubbers and pumps. They also breath the air and are incredibly hearty so there are no worries if your home and someone cleaning at the office or something like that accidentally unplugs it while your away.
 
I know you said no cichlids bit for agression definately a red devil. An 80 would be perfect for one. A real personal fish too.
 
Snakeheads, their very cool. And Oscar wouldnt fit, id definetly say 140g as a minimum. These guys grow to 45cm, even tho 40 is more likely.
 
If snakeheads are legal and available where you live...go for it. The look in their eyes when sizing up prey reminds me of the velociraptors in Jurassic Park.
 
What species if lung fish? I know there is an Aussie or an african, not sure if there are others? Someone posted a pic of a 30" 1 on here a while back but not sure of the species.

Yea I think I'm going to stick FW or brackish I don't think I have the time or funds to commit to a marine set up ATM

Mine was a south American lung about 24-28" long. Was quite happy in a 55. Unfortunately said hi to my idiot cat and the results were not good.
 
I didn't see anyone chime in really on salt. It is costly start up and gets costly with corals and invertebrates but you shouldn't even start there until the setup is at least a year old! But for fish it's just salt, water, heater, light filter(hob) or sump, protein skimmer (not necessary if you want to do weekly water changes) and live rock and sand! I suggest a refractometer and poof! Just with water changes you need to make sure the sg of the new water is the same as the tank. And you need to top off the water every once in a while and you use fresh for that! That's it in a nutshell

Wouldn't a pirhanna be a bit timid if kept alone? Most shoaling fish try to hide a lot if kept alone IME

I've been thinking about a red wolf, I don't know of any others that are small enough for an 80g for life? Are the reds very active?

Not if you get a elongated piranha or a manueli

Another vote for Snakeheads. As DC said, there are many subtropical, very low maintenance species with great color.
Fahakas get too large for an 80g. Mine made my 120g look small after 2 years. Many people find the smaller species of puffers boring since they are usually lurkers, but feeding times are always entertaining.
Wolffish is a good option too.
