holy you've got room for a goliath tiger? Trout are native to streams rivers and lakes with high amounts of oxygen, The movement in the water is more natural to their habitat and helps keep the water oxygenated. Trout require a huge amount of oxygen to live, and cold water. whats the temperature get to in the summer where you live?
I don't have enough room for the goliath for life lol..... I'm just growing him out in a 220 and I'll sell him at a good price if I can get him big.... the temp gets hot in the summer but I use lots of DO w/ air pumps and stuff so idk if the powerhead would help out that much but it couldn't hurt for sure
