The only thing I’m worried about is cleaning the food cause it’s bare bottom so cleaning it is a bit hard also I can’t use a siphon because the setup is on the floor so I could get substrate making it easier to clean smaller uneaten food but any advice on water changes I could try a smaller siphon or cut the current on in half or get a short bucket but any other advice would be helpful
the first thing id like to say is adding substrate makes it allot and i mean allot harder to clean it may look cleaner but it is quite the opposite. all the waste just stays trapped so id recommend keeping it bare bottom or getting sand so that the waste sits ontop of the sand but itll still make it allot more of a pain to clean.
flowerhorns need allot of water changes so you need a siphon so your waterchanges are actually effective at removing debris and just to make it easier on yourself because its hard to make yourself do something on a regular basis that you dont want to do.
id recommend putting the tank on cinderblocks. the siphons i buy from petco come with a small hand pump to start the siphon because it seems no one knows the proper way to do it but i use these to complete waterchanges for the tanks on my floor.
