I need some advice. My husband bought the kids a 29 gallon Top Fin Kit. First mistake he bought a 30 gallon stand instead of a 29 gallon one. Please tell me this is okay . I was skeptical but hubby called Petsmart and Petsupermarket said it was okay. I wanted to replace the Top Fin 30 filter with an Aquaclear 50 because I read it's the best HOB. Hubby brought home a Penguin 75. Should I return the Penguin filter & get the Aquaclear? Is a Penguin 75 overkill for a 29 gallon. It doesn't fit in the cover opening either. I put Tahitian Moon sand & a couple plants from my old tank. My old tank was a 2.5 gallon so this is a big upgrade. Right now I only have 1 old female guppy in there. I'm planning on adding 3 juvenile angelfish and 2 corys once it is cycled. What plants would you suggest & how many? What about driftwood should I get real or fake?
