Hi. i just joined this website today. i started keeping fish a little over a year ago and i am loving the hobby. I have a 100 gallon corner tank and just recently started a 125 standard. I have managed to keep alive 2 oscars a peacock bass a couple of green terrors and one sweet jardini aro. oh and three tinfoil barbs. Iam beginning to get a descent hold on water chemistry and have realized a few errors. was hoping for some sound advice. the local fish stores seem more interested in acting like they know what they are talking about than actually giving sound advice. in my 125 i plan to keep my jardini and any one else he wont anialate. tinfoil barbs seem to do best. the lfs sold me on crushed coral as substrate and i figure out afterward that is not condusive to low ph which i read is best for the jardini. any advice on substrate. fish to keep with him or anything else would be much appreciated. oh i have two clown loaches in with him now but had four a few days ago so.....oh and running an fx6
