Need 8-10" cichlid ideas

  • We are currently upgrading MFK. thanks! -neo
A 9 to 10 inch fish in a 40 gallon breeder? Seriously?
I am in agreement with Duanes all the way on this.I don't think any c/a cichlid should be kept in it long term.
 
 
I find that "rules" on tank size are very limited. The same rule that may apply to a 12" fish does not apply to a 6" fish. While 40 breeders are fantastic tanks that work well as temporary housing as quarantine tanks (even for "large" fish), they are simply not good for long term housing (for those same fish). I'd vote a max of 6" for life in a 40 breeder. If you believe differently, you're welcome to that, but don't expect to get support from most people here on that subject.

Well the inch per gallon is pretty unrealistic in the world of cichlids, the 4X length and 1.5X width guideline is at least manageable and reasonable housing for the fish on a long term basis. I have kept many 12" fish in 75G tanks and it is adequate however the smallest I would go for them.
it's not 1.5X.......it's 4X length, and 2X width

whatever you decide, just keep to 50-80% WC weekly.....and I wouldn't go too aggressive on species.

If you want interactive fish and owner-responsive, perhaps Gymnothorax polyuranadon or Gymnothorax tile would be good for you
 
Thank you for the responses, and I do agree that a 10" fish is really really pushing the envelope. 8" fish alone IMO is very reasonable if the tank is scaped properly.

Thank you for the suggestion on the grammodes; I will look into that further as I have never kept one.
 
Chiapaheros gram modes grow slowly, but will top 10".
I doubt any other fish ould survive with it in such a small tank.
I grew out a pair in a 75gal, and by the time they hit 4-5" the pair had killed at least a dozen other fish.

male above, male below

A friend of mine had success with a pair in a community 220 gal.
 
I have read they are somewhat of a "mini" Dovii....did you find their behavior to be similar to that of a Parachromis?
 
IME they were very shy only darting from cover for food or if another fish got to close to their hide out. Nice looking fish but real skittish
 
Relating their tank behavior to there probable behavior in the wild is quite interesting. In nature due to their slow growth rate theyre often going to be the smaller fish in a given setting which explains their near constant hiding. In the wild a good hiding spot for a small fish is essential to survival therefore they will defend that territory ferociously especially against conspecific.
