This is the 29 gallon tank that I got for free (Yaay!!). It included a filter (which I upgraded due to how noisy it was), a heater, and the wood stand. I have just one question....my half moon betta likes to sit right against the intake area of the filter. The first couple of times I saw him do it I thought he was stuck but he was able to swim away just fine. Could sitting right at the intake for long periods of time cause him harm over time?? Also could this be why he now has a split in his tail? There is 2 decorations that may have caused the split in his tail and they were removed.
