I am planning to have a 5 gallon dwarf puffer tank soon, just need to figure some stuff out first. The tank is going to house 1 DP and maybe some shrimp (I've heard some people have had success with this, any experiences with the DP shrimp combo would be great to hear). I think the hardest part about keeping the DP is going to be the diet, so I was wondering what I could feed him. I was thinking I could toss some MTS in there and wait for them to multiply, and have BBS, freeze-dried food, and baby shrimp for food. My main concern is that the MTS will either multiply past what a single puffer can eat and he'll die of overfeeding, or he'll destroy the population and I'll have rotting snails scattered throughout my tank (causing an ammonia spike). Any advice on this? Also I don't know if it matters for DPs but do they like more horizontal or vertical swimming room? I think that's it for now but I'll undoubtedly have more questions later.
