I dont find all the nastyness toward Nanu neccesary. You two are reminding me of myself. He is just trying to help. However, i agree that Oto's can be kept in smaller tanks. I belive the reason people suggest larger tanks is so there's more algae that can grow.
Now, as far as saltwater. From what ive read (i was going to do a nano saltwater before) its always advised to do the biggest tank you can because of this reason. When our freshwater tanks loose water due to evaporation, its not a big deal right. Well in a saltwater tank, the salt doesnt evaporate, it stays in there. More salt, less water increase salinity which can kill your fish. In a bigger tank, less water leaves and more is left, in smaller tanks, such as my 5.5 gallon that looses 5% about every day, would be hard to keep at the correct salinity.
I dont want to get yelled at also. But i would have told Kiara the same thing Kenny. And i wouldnt sugar coat it. If you sugar coat it, it makes people think "well they said not to but they said it so nicely its like it would be okay with them if i did. If you guys continue with this, OC, Nanu and the others wont respond much to your threads like how OC never post's in mine anymore. I miss her alot, and you would to, shes a sweet woman. Nanu doesn't post in mine hardly either. I guess because i blew up on both of them so much. Same for MK, Bass, Mercedes and all the others who used to. If we keep this up, it'l be us younger less experinced fish keepers fending for ourselfs, scrambling to get the truth and what we need to care for our fish. Trust me, if i could, id go back in time to everytime i blew up and fix it. Cause i miss all the experinced people.
My 2 cents.
