Will these work in a 150 gallon tank

[I Smell Fish]

I currently have the following cichlids and would like to know how long can they be kept in this size tank

Geophagus 5 inches
green sevrum 3 1/2 inches
Fire mouth 3 inches
Blue acara 4 inches
Synspilum cichlid 4 inches
Black Belt Cichlid 4 inches
Pantano Cichlid
Clown loach 6 inches (never comes out)
yoyo loach 4 inches

All depends on how nasty your black belt will get. The size of this stock and their potential size will be fine in the 150, but I know you're not asking but I think compatibility will be the issue you face and not tank size. You've got a possible bruiser with some more laid back cichlids

For the short term maybe. Ideally I would keep one or a pair (of the larger species) only for a 150g with no tankmates other than dithers. I sold my syn because I felt he was too big and unhappy. He was the only large fish in the tank.
But all of these fish grown in the long term would be very overstocked. They don't stay those sizes for long lol.

If they all end up being males, I say anywhere from 1-2 years. Either aggression or in ability to do very large water changes every few days will determine who you will keep in the 150g.

Pantano=Cincelichthys Pearsei? They get enormous.

What's the foot print of the 150?

Agree with the others here. Also your clown loach probably hides all the time because they really thrive with buddies.

What's your upgrade plan?

You've got 3 large cichlids there, the syn, black belt, and pearsei. If you kept one of them and rehomed the others, you would be fine with the stock. I would choose the pearsei to keep and get rid of the Viejas if I were you, pearsei are much friendlier in general. If you want to keep one of the Viejas, keep the sysnpilum. Usually nicer than a maculicauda (black belt).

I agree. You have some large growing fish in there. I'd say strictly from a bioload perspective assuming good filtration and weekly 50% water changes and not factoring in aggression, you can have five or six cichlids that get to a foot long. If you have a spawning pair or aggressive species, that number is reduced.

I have four large fish in a 150 currently. A pair of Johanna pikes and a pair of Green Terrors. I removed the severums due to aggression and torn fins. If I were to add fish, it would only be one or two more max.

Will have to wait and see which one the black belt is since they juveniles seem to all look the same. lol
