I will consider sharing them later, as they are a very good long way from being finished (or even started, really). By May they will be ready to share though! Or perhaps I will post of their progress. We shall see!
With this tank, I am housing a giant betta, so other than the shrimp and pest snails, I won't have anything else in there. If he grows as well as I hope he might, and if he is anything like my current female (who is not giant, but rather huge), I will be able to see teeth meaning that if he bites, he can bite good and do serious damage to any other fish. The shrimp may be eaten, but that is okay.
I am choosing to go with no filter because I really wanted to try something new on a larger tank. I don't have a filter on my 2 gallon because of that fish's heavy fins and a lack of space for one, but in this case, I just wanted to do something very simple, quiet, and relaxed. Also, since there is only one very small hole cut for the heater cord, there is less risk of my shrimp, or fish jumping out, or my cat getting in.
Remember that the tank your fish lives in is his or her's whole world. Ask yourself this question, and answer it honestly: would you choose to live there?
