what is the best bonding agent for fish tanks, like that silicone stuff that they use in glass ten gallon tanks also whats it called ^^' and how much do they cost, also what is better/cheaper Acrylic or glass???
Well...at almost any pet store they will sell "aquarium sealant." Which is just silicone glue. Make sure it is made for fish tanks though. I bought mine for about $5 a tube.
yes that way you know it is safe and chemicals won't hurt fish. You can also find it at walmart if they carry it, my store does but next town over doesn't.
