Hey all, So right now I have a 30gal freshwater fish only setup. In it I've got 17 tiger barbs (6 reg, 6 green, 5 albino - all living happily) and a golden algae eater. I've read on various sites that the algae eater has potential to become a fish sucker, causing problems down the road, but most accounts seem to say this is with larger fish (than barbs). In preparation for the fish getting bigger (they've only been in my 30gal for a month), I went out and got a 55 gallon tank. I'm not a huge huge rush to try to stock it, but we'll see how long I can possibly wait. So I'm looking for some advice on stocking it and a few other things. First off, with 17 tigers and the algae eater - I think I would have a bit more room and would be able to put a few more fishies into the tank. What I think I would ideally like to do is something like this: - 17 tiger barbs (or fewer, if some unfortunately die before then - no casualties since their introduction though) - algae eater - one of the freshwater sharks, preferably one that would live comfortably in a 55gal and wouldn't become too aggressive with the tigers (which is one area where I'm looking for a suggestion on a type) - a few loaches, kuhli or yoyo or something similar and bottom dwelling-like. I don't think that would overstock the tank, but correct me if I'm wrong. One question I have is: Would it be beneficial to have a powerhead in a tank like this? I've never worked with one before, and I've never had anything other than goldfish in tank larger than 30gal, so I don't really know much about powerheads except for what I've read recently. Second question: I've also never tried to have live plants in a tank before but I think I would like to. Would my proposed fish stock be one that destroys, eats, clips, etc. the plants effectively ruining them? Also, in a 55gal tank, would CO2 diffusion be mandatory for success or would I just get enough light, fertilizer, and call it a day? Or should I just experiment with low-light plants in the 30gal after I move the fish to the new tank and bring a more experienced self to plant in the 55gal later on? Lastly: Any suggestions on successfully re-housing the fish from one tank to the other? Assuming the parameters are the same, should I move them all at once - pick up from one and place in the other right away, or should I only move a few at a time? Thanks!
