my 180 sprung a leak compatibility issues?

[nato2k]

At one point I had all of these fish in my 135 but as they got older i separated them anticipating the conflict to be. Now that my 180 sprung a leak they are back together. The fish are:

1x 8-10 inch Silver Arowana, 1x 6ish inch male Vieja Zonatus, 1x 8-10 inch male Managuense, 1x 8 inch female Frontosa, 1x 5-6 inch Tiger Oscar, 1x 3 inch Jewel, 1x 5-6 inch male JD, 1x 4 inch Green Terror, 1x 5 inch Electric Blue Ahli, 2x Yellow Labs(1 male 1 female), 1x 12 inch Red bellied Pacu, 1x 4 inch Green Texas.

its a 135 gal. I have had them together for almost 2 weeks now and it will be another couple of months until I get the tank fixed, if I can. There is a large crack in one of the side panels. I previously had the Americans + arowana + pacu in the 180 and the africans in the 135. So far the only territory disputes have been between the Vieja and Managuense, and sometimes by the Ahli and the Oscar but those havent been bad at all. I have several hiding places for the small and larger fish. The water params were almost identical in both tanks DKH ~120/KH 80/PH ~7.2/Ammonia 0/Nitrite 0/Nitrate 10. Filtration is Rena xp3, 2x Penguin 200, 1x AquaClear 110.

I know these conditions aren't Idea but how bad do you think it will be? How high is that for bio load? If I haven't seen any bad conflicts yet should that be OK? I will be selling the Pacu more than likely to help the bio load of the tank but I dont want to sell any of the other fish, I have had them all since they were babies.

Good decision to sell the pacu. With those lot, your bioload would be very heavy so I would suggest minimizing the feeding rations and keep a close watch for aggression. Do you have a spare tank at the moment? You can use it just in case aggression occurs where an injured fish must be treated immediately or the bully isolated immediately.

How often are you doing water changes at the moment and how much? I would do thrice a week by 50% to cope with their wastes. How is the tank decorated?

i have been doing 2 changes/week at about 35-40%. I do have a 30g hospital tank ready and have been watching for wounds. the tank is decorated with natural rock and driftwood and silica sand for substrate. There are 2.5 large hiding spots(for some reason my Frontosa never liked the large ones and hangs underneath some driftwood that hardly provides any hiding space) which have been claimed by the managuense and the Vieja(both have done quite a bit of excavating too). There are several hiding spots for the smaller fish under the rocks. I can probably get a few more rocks for hiding with the credit i get from the Pacu and 2x 10 inch Pleco's(currently in the hospital tank because of their huge amount of waste).

This picture actually gives you a better idea of the hiding spot on the left. there are tons of smaller caves both front and back on both the formations on the sides along with several small caves in the lava rock.

Nice tank!:)

Nice tank and good luck fixing your 180g.

thanks guys! so far so good. I sold the pacu which helps a lot considering how much he ate alone. there really havent been any conflicts at all, other than anyone who gets close to the opening to the managuense's claimed spot. he just kinda chases them out of the opening but doesnt actually harass them. I was pretty happy I got 40$ credit at my LFS for the pacu and the two common pleco's. so I bought more rocks :D
