In my even moderately lighted tanks I have to add nitrate regularly. This is especially true if the tank is not overcrowded and this tank is not yet stocked. There is nothing to provide nitrate but the cycling ammonia, which is at the levels it should be for that purpose.
Sorry to disagree w/pp on Otos, but their common failure in tanks is not IPs but simple starvation. If a batch of newly received Otos are flat-bellied or hollow-bellied, they are quite possibly doomed due to starvation during holding before shipping. As with many South American sucker-mouth cats, these have specialized gut microbes (but not the same ones the wood-eaters have) which will die off it not fed. They can only replace these in the wild, not in captivity. If they have been starved, they are doomed. Such fish generally die within the first 2-3 weeks. So do not purchase them until they have been in the LFS that long.
But it is correct that Otos do need established and relatively stable tanks. I do not add these to new tanks for at least 2-3 months either.
Nice looking tank, it should suit DPs well.
Thanks RTR.
1) would regularly feeding them Otos with cucumber and algae wafers help?
2) Also, as with your planted tank, does it mean that since i'm going for only 5 DPs in such a heavily planted tank, i would do well to dose NO3 from now on, since ammonia is dropping and nitrate from fishes are insufficient to meet my plants demands. My current lighting is 24w x 4 and is switched on for 8 hours, together with the Co2. I dose Seachem's Excel, Potassium, Iron, Trace and Comprehensive accordingly too.
