I am sizing up from a 10 gallon tank to a 20 gallon long. I bought a from Walmart for the 10 gallon. I've been browsing around on this forum and am confused as to if it is better to go with a glass top or a hood for the new 20 gallon and if I should be looking at fluorescent or LED lights. I aspire to have a planted tank, but haven't gotten there yet with the 10 gallon. Opinions/advice welcomed or if you can point me to any other resources that talk about this topic. Just not sure what all I need to buy for the top to the aquarium. TIA!
