It DOES look like an injury of some sort... Melafix is great to aid in healing, too - but of course the question is where did it come from in the first place - do you think his tunnel or any of his other ornaments are small enough that he could have bumped his head on his way in or out?
No more pacing. Now he's back to doing his dead log impression, to the point where I am regularly poking him with a net to make sure he's still alive. o.O I hate when he does that to me. Eating is back, thank goodness! Eye still looks a tad cloudy but overall, he seems to be doing much better. Sparky thanks you all for your concern and wishes he could give you a big fishy hug but uh, his fins aren't big enough to reach and he might zap you.
Sparky is pleased to report that he feels superb! The trick now is to keep his tank warm enough. We've purchased some insulation to go around it but haven't yet attached it but even just with a piece leaning against the side, the tank is staying at the proper temp.
Soon, so very soon, Sparky will be upgraded to a larger, indoor tank! Can't wait. Was thinking about getting a long 200gal tank and dividing it. One side for the Sparkster and the other side for . . . something else. Black Ghost Knifefish or cichlids.
Ordered Sparky some earthworm pellets from kensfish. He'd better like them, since the shipping almost bankrupted me. Worried about his diet. He needs to eat a variety of foods so he gets all the vitamins and nutrition he needs. But noooo, all he wants are Hikari Massivore Delite pellets. Not the frozen krill or the frozen Ocean Nutrition Formula One or any other fancy foods I got him. Sigh. Sparky, it's like you're eating McDonald's every day.
