Okay so I'm cycling a 50 gallon tank and I have a young 1" Thorichthys aureus in a 20 g hex and just added two Gold Rams (same size as Thorichthys), also have 3 Sterbas Corydoras they will all be moving to the 50 gallon (I know 20ghex sucks) The Thorichthys is a little jerk, chasing the rams and even the cories all the time and displaying colors. Is this just an aggressive fish or just need more room? What tankmates would be suitible in the 50 gallon?
Thanks there's not too much info on him, first post here btw.
