My son has a Marigold Swordtail in a 5g tank that he's simply outgrown. Being that he's a baseball (Phillies) fanatic, I wanted to do a baseball themed tank that would be easy for him to learn to clean and take care of. It has an AquaClear 50 for filtration and I just ordered a Marineland LED hood and a heater for it. We plan to add some more community fish to it in a few weeks. I know this goes against most folk's idea of realistic looking decor, but I thought this was cool and wanted to share. Let me know what you think. The only problem I foresee is the metal springs in the bobbleheads rusting. Will that make the water acidic or anything? I can take the springs out if need be.
