I only got him about a month or 2 ago and he is about 4" long. For the first few weeks he was a permanent fixture on my driftwood. I also dropped a few algae wafers in a few times a week before going to bed. For the past week or so he's been hanging on the glass or the filter intake and I haven't seen him near the wood. Today he's floating. It's a shame because I really liked him. In 20+ years of fishkeeping he was the first non-common pleco I bought. Everyone else is actually doing fine. It's a shame.
