Like it's a bad thing , huh ? Went to the pet shop this week and bought two more tanks. Another 20 high and a 10 gallon. I'm up to six tanks now. My Aplocheilus lineatus Golden Wonder Killifish are fruitful and multiplying rapidly. Need more grow out and breeding space. Six tanks to maintain and propagate a single species ? This is getting out of hand. I'm starting to accumulate spare pumps and heaters but I need some more black sand, a 150 watt submersible heater, a big sponge filter and another siphon hose. The room is getting crowded too. I build my models in there and I have a 1,000 piece jigsaw puzzle half completed. Live foods going on shelves and worm cultures in the closet.
