Hi i have a 125 gal running with peaceful timid cichlids which include keyholes angelfish and uaru but i also have a 55 gal but theres nothing in it and i want it to be like a solitary species tank maybe two vieja argentea. They have some really nice ones at the lfs. I was thinking maybe texas cichlids too but the vieja argentea is very nice i would only put a two in of either or. If you guys dont think its suitable enough what would you recommend in a solitary type set up for a 55 gal. I only want like two fish in there.I also want them to be a decent size and more on the aggressive side because i already have the docile 125 gal. Thanks
